+.SH NAME
+ares_expand_string \- Expand a length encoded string
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_expand_string(const unsigned char *\fIencoded\fP,
+.B      const unsigned char *\fIabuf\fP, int \fIalen\fP, unsigned char **\fIs\fP,
+.B 	int *\fIenclen\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_expand_string
+function converts a length encoded string to a NULL terminated C
+string.  The argument
+.I encoded
+gives the beginning of the encoded string, and the arguments
+.I abuf
+and
+.I alen
+give the containing message buffer (necessary for the processing of
+indirection pointers within the encoded domain name).  The result is
+placed in a NUL-terminated allocated buffer, a pointer to which is
+stored in the variable pointed to by
+.IR s .
+The length of the encoded string is stored in the variable pointed to by
+.I enclen
+so that the caller can advance past the encoded string to read
+further data in the message.
+.SH RETURN VALUES
+.B ares_expand_string
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+Expansion of the encoded string succeeded.
+.TP 15
+.B ARES_EBADSTR
+The encoded string was malformed and could not be expanded.
+.TP 15
+.B ARES_ENOMEM
+Memory was exhausted.

+                     ====================================
+
+The libcurl source code offers a few functions by source only. They are not
+part of the official libcurl API, but the source files might be useful for
+others so apps can optionally compile/build with these sources to gain
+additional functions.
+
+
+strtoofft.[ch]
+==============
+
+ curlx_strtoofft()
+
+   A macro that converts a string containing a number to a curl_off_t number.
+   This might use the curlx_strtoll() function which is provided as source
+   code in strtoofft.c. Note that the function is only provided if no
+   strtoll() (or equivalent) function exist on your platform. If curl_off_t
+   is only a 32 bit number on your platform, this macro uses strtol().
+
+timeval.[ch]
+============
+
+ Provides a 'struct timeval' for platforms that don't have one already, and
+ includes the proper include files for those that have one. Using this will
+ make the output require the 'winmm' lib on Windows (unless WITHOUT_MM_LIB
+ is defined at compile-time).
+
+ curlx_tvnow()
+
+   returns a struct timeval for the current time.
+
+ curlx_tvdiff()
+
+   returns the difference between two timeval structs, in number of
+   milliseconds.
