int symlinkat(const char * oldpath , int newdirfd , const char * newpath );
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
- 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.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
