 Building from git source
 ------------------------
 To prepare the libbsd source tree from git before starting the build process
 some required software needs to be installed:
  GNU autoconf >= 2.67
  GNU automake >= 1.9
  GNU libtool >= 2.0
 After installing the needed software, and running the following command on
 the git tree:
  $ ./autogen
 the source should be roughly equivalent to the distributed tar source.
 Building from tar source
 ------------------------
 The minimum software required to configure and build dpkg from a tarball is:
  C89 compiler
  make
 The following software might be required depending on the system:
  libmd (whenever the libc does not provide the needed digest functions)
 The build process is done by running the usual «./configure; make». To
 see all available configuration options please run «./configure --help».

 .Nm TIMEVAL_TO_TIMESPEC ,

 .Nd time structures conversion macros
 .Sh LIBRARY
 .ds str-Lb-libbsd Utility functions from BSD systems (libbsd, \-lbsd)
 .ds doc-str-Lb-libbsd \*[str-Lb-libbsd]
 .Lb libbsd
 .Sh SYNOPSIS
 .In sys/time.h
 (See
 .Xr libbsd 7
 for include usage.)
 .Ft void
 .Fn TIMEVAL_TO_TIMESPEC "struct timeval *tv" "struct timespec *ts"
 .Ft void
 .Fn TIMESPEC_TO_TIMEVAL "struct timeval *tv" "struct timespec *ts"
 .Sh DESCRIPTION
 The
 .Va timeval
 structure represents elapsed time, in whole seconds,
 and the rest of the elapsed time in microseconds.
 .Pp
 The
 .Va timespec
 structure represents elapsed time, in whole seconds,
 and the rest of the elapsed time in nanoseconds.
 .Pp
 A microsecond is equal to one millionth of a second,
 1000 nanoseconds, or 1/1000 milliseconds.
 To ease the conversions, the macros
 .Fn TIMEVAL_TO_TIMESPEC
 and
 .Fn TIMESPEC_TO_TIMEVAL
 can be used to convert between
 .Em struct timeval
 and
 .Em struct timespec .
 .Sh EXAMPLES
 It can be stressed that the traditional
 .Tn UNIX
 .Va timeval
 and
 .Va timespec
 structures represent elapsed time, measured by the system clock.
 The following sketch implements a function suitable
 for use in a context where the
 .Va timespec
 structure is required for a conditional timeout:
 .Bd -literal -offset indent
 static void
 example(struct timespec *spec, time_t minutes)
 {
 	struct timeval elapsed;
 	(void)gettimeofday(&elapsed, NULL);
 	TIMEVAL_TO_TIMESPEC(&elapsed, spec);
 	/* Add the offset for timeout in minutes. */
 	spec->tv_sec = spec->tv_sec + minutes * 60;
 }
 .Ed
 .Pp
 A better alternative would use the more precise
 .Xr clock_gettime 2 .

 .Sh DESCRIPTION
-The
+This family of functions provides higher quality data than those
-.Nm
+described in
 family of functions provides a cryptographic pseudorandom number
 generator automatically seeded from the system entropy pool and safe to
 use from multiple threads.
 .Nm
 is designed to prevent an adversary from guessing outputs,
 unlike
 .Xr rand 3
 and
 .Xr random 3 ,
 and is faster and more convenient than reading from
 .Pa /dev/urandom
 directly.
 .Pp
 .Fn arc4random
 returns an integer in [0, 2^32) chosen independently with uniform
 distribution.
 .Pp
 .Fn arc4random_uniform
 returns an integer in [0,
 .Fa bound )
 chosen independently with uniform distribution.
 .Pp
 .Fn arc4random_buf
 stores
 .Fa len
 bytes into the memory pointed to by
 .Fa buf ,
 each byte chosen independently from [0, 256) with uniform
 distribution.
 .Pp
 .Fn arc4random_stir
 draws entropy from the operating system and incorporates it into the
 library's PRNG state to influence future outputs.
 .Pp
 .Fn arc4random_addrandom
 incorporates
 .Fa len
 bytes, which must be nonnegative, from the buffer
 .Fa buf ,
 into the library's PRNG state to influence future outputs.
 .Pp
 It is not necessary for an application to call
 .Fn arc4random_stir
 or
 .Fn arc4random_addrandom
 before calling other
 .Nm
 functions.
 The first call to any
 .Nm
 function will initialize the PRNG state unpredictably from the system
 entropy pool.
 .Sh SECURITY MODEL
 The
 .Nm
 functions provide the following security properties against three
 different classes of attackers, assuming enough entropy is provided by
 the operating system:
 .Bl -enum -offset abcd
 .It
 An attacker who has seen some outputs of any of the
 .Nm
 functions cannot predict past or future unseen outputs.
 .It
 An attacker who has seen the library's PRNG state in memory cannot
 predict past outputs.
 .It
 An attacker who has seen one process's PRNG state cannot predict past
 or future outputs in other processes, particularly its parent or
 siblings.
 .El
 .Pp
 One
 .Sq output
 means the result of any single request to an
 .Nm
 function, no matter how short it is.
 .Pp
 The second property is sometimes called
 .Sq forward secrecy ,
 .Sq backtracking resistance ,
 or
 .Sq key erasure after each output .
 .Sh IMPLEMENTATION NOTES
 The
 .Nm
 functions are currently implemented using the ChaCha20 pseudorandom
 function family.
 For any 32-byte string
 .Fa s ,
 .Pf ChaCha20_ Fa s
 is a function from 16-byte strings to 64-byte strings.
 It is conjectured that if
 .Fa s
 is chosen with uniform distribution, then the distribution on
 .Pf ChaCha20_ Fa s
 is indistinguishable to a computationally bounded adversary from a
 uniform distribution on all functions from 16-byte strings to 64-byte
 strings.
 .Pp
 The PRNG state is a 32-byte ChaCha20 key
 .Fa s .
 Each request to
 an
 .Nm
 function
 .Bl -bullet -offset abcd -compact
 .It
 computes the 64-byte quantity
 .Fa x
 =
 .Pf ChaCha20_ Fa s Ns Pq 0 ,
 .It
 splits
 .Fa x
 into two 32-byte quantities
 .Fa s'
 and
 .Fa k ,
 .It
 replaces
 .Fa s
 by
 .Fa s' ,
 and
 .It
 uses
 .Fa k
 as output.
 .El
 .Pp
 .Fn arc4random
 yields the first four bytes of
 .Fa k
 as output directly.
 .Fn arc4random_buf
 either yields up to 32 bytes of
 .Fa k
 as output directly, or, for longer
 requests, uses
 .Fa k
 as a ChaCha20 key and yields the concatenation
 .Pf ChaCha20_ Fa k Ns Pq 0
 ||
 .Pf ChaCha20_ Fa k Ns Pq 1
 || ... as output.
 .Fn arc4random_uniform
 repeats
 .Fn arc4random
 until it obtains an integer in [2^32 %
 .Fa bound ,
 2^32), and reduces that modulo
 .Fa bound .
 .Pp
 The PRNG state is per-thread, unless memory allocation fails inside the
 library, in which case some threads may share global PRNG state with a
 mutex.
 The global PRNG state is zeroed on fork in the parent via
 .Xr pthread_atfork 3 ,
 and the per-thread PRNG state is zeroed on fork in the child via
 .Xr minherit 2
 with
 .Dv MAP_INHERIT_ZERO ,
 so that the child cannot reuse or see the parent's PRNG state.
 The PRNG state is reseeded automatically from the system entropy pool
 on the first use of an
 .Nm
 function after zeroing.
 .Pp
 The first use of an
 .Nm
 function may abort the process in the highly unlikely event that
 library initialization necessary to implement the security model fails.
 Additionally,
 .Fn arc4random_stir
 and
 .Fn arc4random_addrandom
 may abort the process in the highly unlikely event that the operating
 system fails to provide entropy.

 and
 .Xr chroot 2 .
 .Pp
 High quality 32-bit pseudo-random numbers are generated very quickly.
 On each call, a cryptographic pseudo-random number generator is used
 to generate a new result.
 One data pool is used for all consumers in a process, so that consumption
 under program flow can act as additional stirring.
 The subsystem is re-seeded from the kernel random number subsystem using
 .Xr getentropy 2
 on a regular basis, and also upon
 .Xr fork 2 .
 .Pp
 The
 .Fn arc4random
 function returns a single 32-bit value.
 .Pp
 The
 .Fn arc4random_buf
 function fills the region
 .Fa buf
 of length
 .Fa nbytes
 with random data.
 .Pp
 .Fn arc4random_uniform
 will return a single 32-bit value, uniformly distributed but less than
 .Fa upper_bound .
 This is recommended over constructions like
 .Dq Li arc4random() % upper_bound
 as it avoids "modulo bias" when the upper bound is not a power of two.
 In the worst case, this function may consume multiple iterations
 to ensure uniformity; see the source code to understand the problem
 and solution.
 .Pp
 The
 .Fn arc4random_stir
 function reads data from
 .Xr getentropy 2
 and uses it to re-seed the subsystem via
 .Fn arc4random_addrandom .
 .Pp
 There is no need to call
 .Fn arc4random_stir
 before using
 .Fn arc4random
 functions family, since
 they automatically initialize themselves.

 reserved to indicate an error.

 Unfortunately, the library found widespread adoption and the name stuck
 before anyone recognized that it was silly.
 .Pp
 The signature of
 .Fn arc4random_addrandom
 is silly.
 There is no reason to require casts or accept negative lengths:
 it should take a
 .Vt void *
 buffer and a
 .Vt size_t
 length.
 But it's too late to change that now.
 .Pp
 .Fn arc4random_uniform
 does not help to choose integers in [0,
 .Fa n )
 uniformly at random when
 .Fa n
 > 2^32.
 .Pp
 The security model of
 .Nm
 is stronger than many applications need, and stronger than other
 operating systems provide.
 For example, applications encrypting messages with random, but not
 secret, initialization vectors need only prevent an adversary from
 guessing future outputs, since past outputs will have been published
 already.
 .Pp
 On the one hand,
 .Nm
 could be marginally faster if it were not necessary to prevent an
 adversary who sees the state from predicting past outputs.
 On the other hand, there are applications in the wild that use
 .Nm
 to generate key material, such as OpenSSH, so for the sake of
 .Nx
 users it would be imprudent to weaken the security model.
 On the third hand, relying on the security model of
 .Nm
 in
 .Nx
 may lead you to an unpleasant surprise on another operating system
 whose implementation of
 .Nm
 has a weaker security model.
 .Pp
 One may be tempted to create new APIs to accommodate different
 security models and performance constraints without unpleasant
 surprises on different operating systems.
 This should not be done lightly, though, because there are already too
 many different choices, and too many opportunities for programmers to
 reach for one and pick the wrong one.

 .Sh DESCRIPTION
 The
 .Fn getprogname
 returns a string with the current program name,
 excluding any directory component.
 The function will return
 .Dv NULL
 if it was unable to get the program name from any known source.
 .Pp
 The
 .Fn setprogname
 function sets the current program name,
 stripping any directory component prefix.
 The function will keep a reference to the passed string pointer,
 so it must not be freed or modified while these functions might
 be called.
 .Pp
 The implementations on most BSDs will try to initialize the program name
 at program startup time, and
 .Nm libbsd
 will try to infer it from various known sources depending on the
 target system.
 But it is not a portable assumption that the program name will be set
 without calling
 .Fn setprogname ,
 so portable programs should always call it after starting up.
 .Sh SEE ALSO
 .Xr setproctitle 3bsd .
 .Sh HISTORY
 The
 .Fn setprogname
 and
 .Fn setprogname
 functions manipulate the name of the current program.
 They are used by error-reporting routines to produce
 consistent output.
 .Pp
 The
 .Fn getprogname
-functions first appeared in
+function returns the name of the program.
 If the name has not been set yet, it will return
 .Dv NULL .
 .Pp
 The
 .Fn setprogname
 function sets the name of the program to be the last component of the
 .Fa progname
 argument.
 Since a pointer to the given string is kept as the program name,
 it should not be modified for the rest of the program's lifetime.
 .Pp
 In
 .Fx ,
 the name of the program is set by the start-up code that is run before
 .Fn main ;
 thus,
 running
 .Fn setprogname
 is not necessary.
 Programs that desire maximum portability should still call it;
 on another operating system,
 these functions may be implemented in a portability library.
 Calling
 .Fn setprogname
 allows the aforementioned library to learn the program name without
 modifications to the start-up code.

 .Sh DESCRIPTION
 The
 .Fn user_from_uid
 function returns the user name associated with the argument
 .Fa uid .
 The user name is cached so that multiple calls with the same
 .Fa uid
 do not require additional calls to
 .Xr getpwuid 3 .
 If there is no user associated with the
 .Fa uid ,
 a pointer is returned
 to a string representation of the
 .Fa uid ,
 unless the argument
 .Fa nouser
 is non-zero, in which case a null pointer is returned.
 .Pp
 The
 .Fn uid_from_user
 function returns the user ID associated with the argument
 .Fa name .
 The user ID is cached so that multiple calls with the same
 .Fa name
 do not require additional calls to
 .Xr getpwnam 3 .
 If there is no user ID associated with the
 .Fa name ,
 the
 .Fn uid_from_user
 function returns -1;
 otherwise it stores the user ID at the location pointed to by
 .Fa uid
 and returns 0.
 .Pp
 The
 .Fn group_from_gid
 function returns the group name associated with the argument
 .Fa gid .
 The group name is cached so that multiple calls with the same
 .Fa gid
 do not require additional calls to
 .Xr getgrgid 3 .
 If there is no group associated with the
 .Fa gid ,
 a pointer is returned
 to a string representation of the
 .Fa gid ,
 unless the argument
 .Fa nogroup
 is non-zero, in which case a null pointer is returned.
 .Pp
 The
 .Fn gid_from_group
 function returns the group ID associated with the argument
 .Fa name .
 The group ID is cached so that multiple calls with the same
 .Fa name
 do not require additional calls to
 .Xr getgrnam 3 .
 If there is no group ID associated with the
 .Fa name ,
 the
 .Fn gid_from_group
 function returns -1;
 otherwise it stores the group ID at the location pointed to by
 .Fa gid
 and returns 0.

 .Fn calloc .
 If
 .Fa ptr
 is not
 .Dv NULL ,
 .Fa oldnmemb
 must be a value such that
 .Fa oldnmemb

 .Fa size
 is the size of the earlier allocation that returned
 .Fa ptr ,
 otherwise the behavior is undefined.
 The
 .Fn freezero
 function is similar to the
 .Fn free
 function except it ensures memory is explicitly discarded.
 If
 .Fa ptr
 is
 .Dv NULL ,
 no action occurs.
 If
 .Fa ptr
 is not
 .Dv NULL ,
 the
 .Fa size
 argument must be equal to or smaller than the size of the earlier allocation
 that returned

 If multiplying
 .Fa nmemb
 and
 .Fa size
 results in integer overflow,
 .Fn reallocarray
 and

 return
 .Dv NULL
 and set
 .Va errno
 to

 .Pp
 If
 .Fa ptr
 is not
 .Dv NULL
 and multiplying
 .Fa oldnmemb
 and
 .Fa size
 results in integer overflow
 .Fn recallocarray
 returns
 .Dv NULL
 and sets
 .Va errno
 to
 .Er EINVAL .
 .Sh IDIOMS
 Consider
 .Fn calloc
 or the extensions
 .Fn reallocarray
 and
 .Fn recallocarray
 when there is multiplication in the
 .Fa size
 argument of
 .Fn malloc
 or
 .Fn realloc .
 For example, avoid this common idiom as it may lead to integer overflow:
 .Bd -literal -offset indent
 if ((p = malloc(num * size)) == NULL)
 	err(1, NULL);
 .Ed
 .Pp
 A drop-in replacement is
 .Fn reallocarray :
 .Bd -literal -offset indent
 if ((p = reallocarray(NULL, num, size)) == NULL)
 	err(1, NULL);
 .Ed
 .Pp
 Alternatively,
 .Fn calloc
 may be used at the cost of initialization overhead.
 .Pp
 When using
 .Fn realloc ,
 be careful to avoid the following idiom:
 .Bd -literal -offset indent
 size += 50;
 if ((p = realloc(p, size)) == NULL)
 	return (NULL);
 .Ed
 .Pp
 Do not adjust the variable describing how much memory has been allocated
 until the allocation has been successful.
 This can cause aberrant program behavior if the incorrect size value is used.
 In most cases, the above sample will also result in a leak of memory.
 As stated earlier, a return value of
 .Dv NULL
 indicates that the old object still remains allocated.
 Better code looks like this:
 .Bd -literal -offset indent
 newsize = size + 50;
 if ((newp = realloc(p, newsize)) == NULL) {
 	free(p);
 	p = NULL;
 	size = 0;
 	return (NULL);
 }
 p = newp;
 size = newsize;
 .Ed
 .Pp
 As with
 .Fn malloc ,
 it is important to ensure the new size value will not overflow;
 i.e. avoid allocations like the following:
 .Bd -literal -offset indent
 if ((newp = realloc(p, num * size)) == NULL) {
 	...
 .Ed
 .Pp
 Instead, use
 .Fn reallocarray :
 .Bd -literal -offset indent
 if ((newp = reallocarray(p, num, size)) == NULL) {
 	...
 .Ed
 .Pp
 Calling
 .Fn realloc
 with a
 .Dv NULL
 .Fa ptr
 is equivalent to calling
 .Fn malloc .
 Instead of this idiom:
 .Bd -literal -offset indent
 if (p == NULL)
 	newp = malloc(newsize);
 else
 	newp = realloc(p, newsize);
 .Ed
 .Pp
 Use the following:
 .Bd -literal -offset indent
 newp = realloc(p, newsize);
 .Ed
 .Pp
 The
 .Fn recallocarray
 function should be used for resizing objects containing sensitive data like
 keys.
 To avoid leaking information,
 it guarantees memory is cleared before placing it on the internal free list.
 Deallocation of such an object should be done by calling
 .Fn freezero .

 .In inttypes.h
 (See
 .Xr libbsd 7
 for include usage.)

 .Fc
 .Sh DESCRIPTION
 The
 .Fn strtoi
 function converts the string in
 .Fa nptr
 to an
 .Ft intmax_t
 value.
 The
 .Fn strtoi
 function uses internally
 .Xr strtoimax 3
 and ensures that the result is always in the range [
 .Fa lo ..
 .Fa hi
 ].
 In addition it always places
 .Dv 0
 on success or a conversion status in the
 .Fa rstatus
 argument, avoiding the
 .Dv errno
 gymnastics the other functions require.
 The
 .Fa rstatus
 argument can be
 .Dv NULL
 if conversion status is to be ignored.
 .Pp
 The string may begin with an arbitrary amount of white space
 (as determined by
 .Xr isspace 3 )
 followed by a single optional
 .Ql +
 or
 .Ql -
 sign.
 If
 .Fa base
 is zero or 16,
 the string may then include a
 .Ql 0x
 or
 .Ql 0X
 prefix,
 and the number will be read in base 16; otherwise,
 .\" if the
 .\" .Fa base
 .\" is zero or 2,
 .\" the string may then include a
 .\" .Ql 0b
 .\" or
 .\" .Ql 0B
 .\" prefix,
 .\" and the number will be read in base 2; otherwise,
 a zero
 .Fa base
 is taken as 10 (decimal) unless the next character is
 .Ql 0 ,
 in which case it is taken as 8 (octal).
 .Pp
 The remainder of the string is converted to an
 .Em intmax_t
 value in the obvious manner,
 stopping at the end of the string
 or at the first character which is not a valid digit
 in the given base.
 (In bases above 10, the letter
 .Ql A
 in either upper or lower case
 represents 10,
 .Ql B
 represents 11, and so forth, with
 .Ql Z
 representing 35.)
 .Pp
 If
 .Fa endptr
 is non-nil,
 .Fn strtoi
 stores the address of the first invalid character in
 .Fa *endptr .
 If there were no digits at all, however,
 .Fn strtoi
 stores the original value of
 .Fa nptr
 in
 .Fa *endptr .
 (Thus, if
 .Fa *nptr
 is not
 .Ql \e0
 but
 .Fa **endptr
 is
 .Ql \e0
 on return, the entire string was valid.)
 .Sh RETURN VALUES
 The
 .Fn strtoi
 function
 always returns the closest value in the range specified by
 the
 .Fa lo
 and
 .Fa hi
 arguments.
 .Pp
 The
 .Va errno
 value is guaranteed to be left unchanged.
 .Pp
 Errors are stored as the conversion status in the
 .Fa rstatus
 argument.
 .Sh EXAMPLES
 The following example will always return a number in
 .Dv [1..99]
 range no matter what the input is, and warn if the conversion failed.
 .Bd -literal -offset indent
 int e;
 intmax_t lval = strtoi(buf, NULL, 0, 1, 99, &e);
 if (e)
 	warnc(e, "conversion of `%s' to a number failed, using %jd",
 	    buf, lval);
 .Ed
 .Sh ERRORS
 .Bl -tag -width Er
 .It Bq Er ECANCELED
 The string did not contain any characters that were converted.
 .It Bq Er EINVAL
 The
 .Ar base
 is not between 2 and 36 and does not contain the special value 0.
 .It Bq Er ENOTSUP
 The string contained non-numeric characters that did not get converted.
 In this case,
 .Fa endptr
 points to the first unconverted character.
 .It Bq Er ERANGE
 The given string was out of range; the value converted has been clamped;
 or the range given was invalid, i.e.
 .Fa lo
 >
 .Fa hi .
 .El
 .Pp
 The range check is more important than the unconverted characters check,
 and it is performed first.
 If a program needs to know if there were unconverted characters when an
 out of range number has been provided, it needs to supply and test
 .Fa endptr.

 .Fn strtou
 stores the original value of
 .Fa nptr
 in
 .Fa *endptr .
 (Thus, if
 .Fa *nptr
 is not
 .Ql \e0
 but
 .Fa **endptr
 is
 .Ql \e0
 on return, the entire string was valid.)
 .Sh RETURN VALUES
 The
 .Fn strtou
 function
 always returns the closest value in the range specified by
 the
 .Fa lo
 and
 .Fa hi
 arguments.
 .Pp
 The
 .Va errno
 value is guaranteed to be left unchanged.
 .Pp
 Errors are stored as the conversion status in the
 .Fa rstatus
 argument.
 .Sh EXAMPLES
 The following example will always return a number in
 .Dv [1..99]
 range no matter what the input is, and warn if the conversion failed.
 .Bd -literal -offset indent
 int e;
 uintmax_t lval = strtou(buf, NULL, 0, 1, 99, &e);
 if (e)
 	warnc(e, "conversion of `%s' to a number failed, using %ju",
 	    buf, lval);
 .Ed
 .Sh ERRORS
 .Bl -tag -width Er
 .It Bq Er ECANCELED
 The string did not contain any characters that were converted.
 .It Bq Er EINVAL
 The
 .Ar base
 is not between 2 and 36 and does not contain the special value 0.
 .It Bq Er ENOTSUP
 The string contained non-numeric characters that did not get converted.
 In this case,
 .Fa endptr
 points to the first unconverted character.
 .It Bq Er ERANGE
 The given string was out of range; the value converted has been clamped;
 or the range given was invalid, i.e.
 .Fa lo
 >
 .Fa hi .
 .El
 .Pp
 The range check is more important than the unconverted characters check,
 and it is performed first.
 If a program needs to know if there were unconverted characters when an
 out of range number has been provided, it needs to supply and test
 .Fa endptr.

 .ds str-Lb-libbsd Utility functions from BSD systems (libbsd, \-lbsd)

 .Sh SYNOPSIS
 .In sys/time.h
 (See
 .Xr libbsd 7
 for include usage.)
 .Ft void
 .Fn TIMEVAL_TO_TIMESPEC "struct timeval *tv" "struct timespec *ts"
 .Ft void
 .Fn TIMESPEC_TO_TIMEVAL "struct timeval *tv" "struct timespec *ts"
 .Sh DESCRIPTION
 The
 .In sys/time.h
 header, included by
 .In time.h ,
 defines various structures related to time and timers.
 .Bl -enum -offset 1n
 .It
 The following structure is used by
 .Xr gettimeofday 2 ,
 among others:
 .Bd -literal -offset indent
 struct timeval {
 	time_t		tv_sec;
 	suseconds_t	tv_usec;
 };
 .Ed
 .Pp
 The
 .Va tv_sec
 member represents the elapsed time, in whole seconds.
 The
 .Va tv_usec
 member captures rest of the elapsed time,
 represented as the number of microseconds.
 .It
 The following structure is used by
 .Xr nanosleep 2 ,
 among others:
 .Bd -literal -offset indent
 struct timespec {
 	time_t		tv_sec;
 	long		tv_nsec;
 };
 .Ed
 .Pp
 The
 .Va tv_sec
 member is again the elapsed time in whole seconds.
 The
 .Va tv_nsec
 member represents the rest of the elapsed time in nanoseconds.
 .Pp
 A microsecond is equal to one millionth of a second,
 1000 nanoseconds, or 1/1000 milliseconds.
 To ease the conversions, the macros
 .Fn TIMEVAL_TO_TIMESPEC
 and
 .Fn TIMESPEC_TO_TIMEVAL
 can be used to convert between
 .Em struct timeval
 and
 .Em struct timespec .
 .El
 .Sh EXAMPLES
 It can be stressed that the traditional
 .Tn UNIX
 .Va timeval
 and
 .Va timespec
 structures represent elapsed time, measured by the system clock.
 The following sketch implements a function suitable
 for use in a context where the
 .Va timespec
 structure is required for a conditional timeout:
 .Bd -literal -offset indent
 static void
 example(struct timespec *spec, time_t minutes)
 {
 	struct timeval elapsed;
 	(void)gettimeofday(&elapsed, NULL);
 	_DIAGASSERT(spec != NULL);
 	TIMEVAL_TO_TIMESPEC(&elapsed, spec);
 	/* Add the offset for timeout in minutes. */
 	spec->tv_sec = spec->tv_sec + minutes * 60;
 }
 .Ed
 .Pp
 A better alternative would use the more precise
 .Xr clock_gettime 2 .

 .Pp
 The macros
 .Fn RB_FOREACH_SAFE
 and
 .Fn RB_FOREACH_REVERSE_SAFE
 traverse the tree referenced by head
 in a forward or reverse direction respectively,
 assigning each element in turn to np.
 However, unlike their unsafe counterparts,
 they permit both the removal of np
 as well as freeing it from within the loop safely
 without interfering with the traversal.
 .Pp
 The
 .Fn RB_EMPTY
 macro should be used to check whether a red-black tree is empty.
 .Sh EXAMPLES
 The following example demonstrates how to declare a red-black tree
 holding integers.
 Values are inserted into it and the contents of the tree are printed
 in order.
 Lastly, the internal structure of the tree is printed.

 .Sh MULTIBYTE CHARACTER SUPPORT
 These functions support multibyte character input.
 The encoding conversion is influenced by the setting of the

 environment variable which defines the set of characters
 that can be copied without encoding.
 .Pp
 If

 When 8-bit data is present in the input,

 If the locales of the data and the conversion are mismatched,
 multibyte character recognition may fail and encoding will be performed
 byte-by-byte instead.
