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

       futimes, lutimes - change file timestamps

       #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

       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.

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

       Errors  are  as  for  utimes(2),  with  the  following  additions   for

       EBADF  fd is not a valid file descriptor.

       ENOSYS The /proc filesystem 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

       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.

   Multithreading (see pthreads(7))
       The futimes() and lutimes() functions are thread-safe.

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