- Add getdelim(), getline(), stpncpy(), strnlen(), wcsnlen(),

  wcscasecmp(), and wcsncasecmp().
- Make some previously non-standard extensions visible
  if POSIX_VISIBLE >= 200809.
- Use restrict qualifiers in stpcpy().
- Declare off_t and size_t in stdio.h.
- Bump __FreeBSD_version in case the new symbols (particularly
  getline()) cause issues with ports.

+.Dt GETLINE 3
+.Os
+.Sh NAME
+.Nm getdelim ,
+.Nm getline
+.Nd get a line from a stream
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.Fd "#define _WITH_GETLINE"
+.In stdio.h
+.Ft ssize_t
+.Fn getdelim "char ** restrict linep" "size_t * restrict linecapp" "int delimiter" " FILE * restrict stream"
+.Ft ssize_t
+.Fn getline "char ** restrict linep" "size_t * restrict linecapp" " FILE * restrict stream"
+.Sh DESCRIPTION
+The
+.Fn getdelim
+function reads a line from
+.Fa stream ,
+delimited by the character
+.Fa delimiter .
+The
+.Fn getline
+function is equivalent to
+.Fn getdelim
+with the newline character as the delimiter.
+The delimiter character is included as part of the line, unless
+the end of the file is reached.
+The caller may provide a pointer to a malloc buffer for the line in
+.Fa *linep ,
+and the capacity of that buffer in
+.Fa *linecapp ;
+if
+.Fa *linecapp
+is 0, then
+.Fa *linep
+is treated as
+.Dv NULL .
+These functions may expand the buffer as needed, as if via
+.Fn realloc ,
+and update
+.Fa *linep
+and
+.Fa *linecapp
+accordingly.
+.Sh RETURN VALUES
+The
+.Fn getdelim
+and
+.Fn getline
+functions return the number of characters written, excluding the
+terminating
+.Dv NUL .
+The value \-1 is returned if an error occurs.
+.Sh EXAMPLES
+The following code fragment reads lines from a file and
+writes them to standard output.
+The
+.Fn fwrite
+function is used in case the line contains embedded
+.Dv NUL
+characters.
+.Bd -literal -offset indent
+char *line = NULL;
+size_t linecap = 0;
+ssize_t linelen;
+while ((linelen = getline(&line, &linecap, fp)) > 0)
+	fwrite(line, linelen, 1, stdout);
+.Ed
+.Sh COMPATIBILITY
+Many application writers used the name
+.Va getline
+before the
+.Fn getline
+function was introduced in
+.St -p1003.1 ,
+so a prototype is not provided by default in order to avoid
+compatibility problems.
+Applications that wish to use the
+.Fn getline
+function described herein should either request a strict
+.St -p1003.1-2008
+environment by defining the macro
+.Dv _POSIX_C_SOURCE
+to the value 200809 or greater, or by defining the macro
+.Dv _WITH_GETLINE ,
+prior to the inclusion of
+.In stdio.h .
+For compatibility with GNU libc, defining either
+.Dv _BSD_SOURCE
+or
+.Dv _GNU_SOURCE
+prior to the inclusion of
+.In stdio.h
+will also make
+.Fn getline
+available.
+.Sh ERRORS
+These functions may fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+Either
+.Fa linep
+or
+.Fa linecapp
+is
+.Dv NULL .
+.It Bq Er EOVERFLOW
+No delimiter was found in the first
+.Dv SSIZE_MAX
+characters.
+.El
+.Pp
+These functions may also fail for any of the errors specified for
+.Fn fgets
+and
+.Fn malloc .
+.Sh SEE ALSO
+.Xr fgetln 3 ,
+.Xr fgets 3 ,
+.Xr malloc 3
+.Sh STANDARDS
+The
+.Fn getdelim
+and
+.Fn getline
+functions conform to
+.St -p1003.1-2008 .
+.Sh HISTORY
+These routines first appeared in
+.Fx 8.0 .
+.Sh BUGS
+There are no wide character versions of
+.Fn getdelim
+or
+.Fn getline .
