#include <fcntl.h> /* Definition of AT_* constants */ #include <sys/time.h>
int futimesat(int dirfd, const char *pathname, const struct timeval times);
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. (See openat(2) for an explanation of why the dirfd argument is useful.)
- pathname is relative but dirfd is neither AT_FDCWD nor a valid file descriptor.
- pathname is relative and dirfd is a file descriptor referring to a file other than a directory.
A similar system call exists on Solaris.
