.SH NAME
.BR utimes
\- set file access and modification times
.SH SYNOPSIS
#include <sys/time.h>
.sp 1
int
\fButimes\fR (const char *\fIfile\fR, const struct timeval *\fItimes\fR);
.SH DESCRIPTION
The
.BR utimes 
function sets the access and modification times of the named file from
the structures in the argument array
.IR times .
.LP
The first structure is the access time, and the second is the modification
time.
.LP
If the times are specified (the
.I times
argument is non-NULL)
the caller must be the owner of the file or be the super-user.
.LP
If the times are not specified (the
.I times
argument is
.BR NULL )
the caller must be the owner of the file, have permission to
write the file, or be the super-user.
.SH RETURN VALUES
Upon successful completion, a value of 0 is returned.
Otherwise, a value of -1 is returned and
.IR errno
is set to indicate the error.
.SH ERRORS
.BR Utimes 
may fail and return any error that may be returned by
.BR __C2GSMALLOC (3)
or the GS/OS system calls
.BR GetFileInfoGS
or
.BR SetFileInfoGS .
.SH BUGS
The restrictions on ownership listed above are not enforced under
GNO since there is no concept of file ownership.

function call appeared in 4.2BSD.
