FUTIMES(3)		   Linux Programmer's Manual		    FUTIMES(3)

NAME
       futimes,	lutimes	- change file timestamps

SYNOPSIS
       #include	<sys/time.h>

       int futimes(int fd, const struct	timeval	tv[2]);

       int lutimes(const char *filename, const struct timeval tv[2]);

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

       futimes(), lutimes(): _BSD_SOURCE

DESCRIPTION
       futimes()  changes  the	access and modification	times of a file	in the
       same way	as utimes(2), with the difference that the  file  whose	 time-
       stamps are to be	changed	is specified via a file	descriptor, fd,	rather
       than via	a pathname.

       lutimes() changes the access and	modification times of a	 file  in  the
       same way	as utimes(2), with the difference that if filename refers to a
       symbolic	link, then the link is not dereferenced:  instead,  the	 time-
       stamps of the symbolic link are changed.

RETURN VALUE
       On  success,  zero is returned.	On error, -1 is	returned, and errno is
       set appropriately.

ERRORS
       Errors are as for utimes(2),  with  the	following  additions  for  fu-
       times():

       EBADF  fd is not	a valid	file descriptor.

       ENOSYS The /proc	file system could not be accessed.

       The following additional	error may occur	for lutimes():

       ENOSYS The  kernel does not support this	call; Linux 2.6.22 or later is
	      required.

VERSIONS
       futimes() is available since glibc 2.3.	lutimes() is  available	 since
       glibc 2.6, and is implemented using the utimensat(2) system call, which
       is supported since kernel 2.6.22.

CONFORMING TO
       These functions are not specified in any	standard.  Other  than	Linux,
       they are	available only on the BSDs.
