+.Sh DESCRIPTION
+The
+.Fn fgetwln
+function
+returns a pointer to the next line from the stream referenced by
+.Fa stream .
+This line is
+.Em not
+a standard wide character string as it does not end with a terminating
+null wide character.
+The length of the line, including the final newline,
+is stored in the memory location to which
+.Fa len
+points.
+(Note, however, that if the line is the last
+in a file that does not end in a newline,
+the returned text will not contain a newline.)
+.Sh RETURN VALUES
+Upon successful completion a pointer is returned;
+this pointer becomes invalid after the next
+.Tn I/O
+operation on
+.Fa stream
+(whether successful or not)
+or as soon as the stream is closed.
+Otherwise,
+.Dv NULL
+is returned.
+The
+.Fn fgetwln
+function
+does not distinguish between end-of-file and error; the routines
+.Xr feof 3
+and
+.Xr ferror 3
+must be used
+to determine which occurred.
+If an error occurs, the global variable
+.Va errno
+is set to indicate the error.
+The end-of-file condition is remembered, even on a terminal, and all
+subsequent attempts to read will return
+.Dv NULL
+until the condition is
+cleared with
+.Xr clearerr 3 .
+.Pp
+The text to which the returned pointer points may be modified,
+provided that no changes are made beyond the returned size.
+These changes are lost as soon as the pointer becomes invalid.
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er EBADF
+The argument

+By default, if a character is escaped, both it and the preceding escape

+The meaning of the arguments is as follows:

+.It Fa stream
+The stream to read from.
+.It Fa len
+If not
+.Dv NULL ,
+the length of the string is stored in the memory location to which it
+points.

+If not
+.Dv NULL ,
+the value of the memory location to which is pointed to, is incremented
+by the number of lines actually read from the file.
+.It Fa delim
+Contains the escape, continuation, and comment characters.
+If a character is
+.Dv NUL
+then processing for that character is disabled.
+If
+.Dv NULL ,
+all characters default to values specified below.
+The contents of
+.Fa delim
+is as follows:
+.Bl -tag -width "delim[0]"
+.It Fa delim[0]
+The escape character, which defaults to
+.Cm \e ,
+is used to remove any special meaning from the next character.
+.It Fa delim[1]
+The continuation character, which defaults to
+.Cm \e ,
+is used to indicate that the next line should be concatenated with the
+current one if this character is the last character on the current line
+and is not escaped.
+.It Fa delim[2]
+The comment character, which defaults to
+.Cm # ,
+if not escaped indicates the beginning of a comment that extends until the
