NAME 🖥️ lutimes 🖥️

change file timestamps

LIBRARY

Standard C library (libc, -lc)

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():

    Since glibc 2.19:
        _DEFAULT_SOURCE
    glibc 2.19 and earlier:
        _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 to indicate the error.

ERRORS

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.

ENOSYS
The kernel does not support this call; Linux 2.6.22 or later is required.
