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.
