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



 

NAME


       futimes, lutimes - change file timestamps

 

SYNOPSIS


       #include 

       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  times-
       tamps  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  times-
       tamps 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.
