NAME
symlinkat - create a symbolic link relative to a directory file descriptorSYNOPSIS
#define _ATFILE_SOURCE #include <stdio.h> int symlinkat(const char *oldpath, int newdirfd, const char *newpath);
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 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.
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.CONFORMING TO
This system call is non-standard but is proposed for inclusion in a future revision of POSIX.1.NOTES
