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  timestamps  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 timestamps 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 futimes():

       EBADF  fd is not a valid file descriptor.

       ENOSYS The /proc file system could not be accessed.

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  only
       available on the BSDs.
