futimes(3)              Library Functions Manual              futimes(3)

ИМЯ

       futimes, lutimes - change file timestamps

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #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():
           Since glibc 2.19:
               _DEFAULT_SOURCE
           glibc 2.19 and earlier:
               _BSD_SOURCE

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       On success, zero is returned.  On error, -1 is returned, and
       errno is set to indicate the error.

ОШИБКИ

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

       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 required.
