NAME
utimes
- set file access and modification times
SYNOPSIS
Fd #include <sys/time.h>
Ft int
Fn utimes const char *file const struct timeval *times
DESCRIPTION
The
Fn utimes
function sets the access and modification times of the named file.
If
Fa times
is
NULL
the access and modification times are set to the current time.
The caller must be the owner of the file, have permission to
write the file, or be the super-user.
If
Fa times
is
non- NULL ,
it is assumed to point to an array of two timeval structures.
The access time is set to the value of the first element, and the
modification time is set to the value of the second element.
The caller must be the owner of the file or be the super-user.
In either case, the inode-change-time of the file is set to the current
time.
RETURN VALUES
Upon successful completion, a value of 0 is returned.
Otherwise, a value of -1 is returned and
errno
is set to indicate the error.
