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

       symlinkat  -  create  a  symbolic  link  relative  to  a directory file

       #define _ATFILE_SOURCE
       #include <fcntl.h> /* Definition of AT_* constants */
       #include <stdio.h>

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

       The symlinkat() system call operates in exactly the same  way  as  sym-
       link(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 pathname).

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

       If newpath is absolute, then newdirfd is ignored.

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

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

       EBADF  newdirfd is not a valid file descriptor.

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

       symlinkat() was added to Linux in kernel 2.6.16.

       This  system  call  is  non-standard but is proposed for inclusion in a
       future revision of POSIX.1.

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