|
|
.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.
