SYMLINKAT(2)			    Linux Programmer's Manual			     SYMLINKAT(2)

NAME
       symlinkat - create a symbolic link relative to a directory file descriptor

SYNOPSIS
       #include <fcntl.h> /* Definition of AT_* constants */
       #include <unistd.h>

       int symlinkat(const char *oldpath, int newdirfd, const char *newpath);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       symlinkat():
	   Since glibc 2.10:
	       _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
	   Before glibc 2.10:
	       _ATFILE_SOURCE

DESCRIPTION
       The symlinkat() system call operates in exactly the same way as symlink(2), except for the
       differences described in this manual page.

       If the pathname given in newpath is relative, then  it  is  interpreted	relative  to  the
       directory referred to by the file descriptor newdirfd (rather than relative to the current
       working directory of the calling process, as is done by symlink(2) for  a  relative  path-
       name).

       If  newpath is relative and newdirfd is the special value AT_FDCWD, then newpath is inter-
       preted relative to the current working directory of the calling process (like symlink(2)).

       If newpath is absolute, then newdirfd is ignored.

RETURN VALUE
       On success, symlinkat() returns 0.  On error, -1 is returned and errno is set to  indicate
       the error.

ERRORS
       The  same  errors that occur for symlink(2) can also occur for symlinkat().  The following
       additional errors can occur for symlinkat():

       EBADF  newdirfd is not a valid file descriptor.

       ENOTDIR
	      newpath is relative and newdirfd is a file descriptor referring  to  a  file  other
	      than a directory.

VERSIONS
       symlinkat()  was  added	to  Linux in kernel 2.6.16; library support was added to glibc in
       version 2.4.

CONFORMING TO
       POSIX.1-2008.

NOTES
       See openat(2) for an explanation of the need for symlinkat().
