|FUTIMESAT(2)||Linux Programmer's Manual||FUTIMESAT(2)|
NAME¶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);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
DESCRIPTION¶This system call is obsolete. Use utimensat(2) instead.
RETURN VALUE¶On success, futimesat() returns a 0. On error, -1 is returned and errno is set to indicate the error.
ERRORS¶The same errors that occur for utimes(2) can also occur for futimesat(). The following additional errors can occur for futimesat():
- dirfd is not a valid file descriptor.
- pathname is relative and dirfd is a file descriptor referring to a file other than a directory.
VERSIONS¶futimesat() was added to Linux in kernel 2.6.16; library support was added to glibc in version 2.4.
CONFORMING TO¶This system call is nonstandard. It was implemented from a specification that was proposed for POSIX.1, but that specification was replaced by the one for utimensat(2).
Glibc Notes¶If pathname is NULL, then the glibc futimesat() wrapper function updates the times for the file referred to by dirfd.
