futimesat - change timestamps of a file relative to a directory file descriptor

#include <fcntl.h> /* Definition of AT_* constants */
#include <sys/time.h>

int futimesat(int dirfd, const char *pathname,
 const struct timeval times[2]);

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

This system call is obsolete. Use utimensat(2) instead.

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

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

If pathname is relative and dirfd is the special value AT_FDCWD, then pathname is interpreted relative to the current working directory of the calling process (like utimes(2)).

If pathname is absolute, then dirfd is ignored.

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