.SH DESCRIPTION
.B dpns_setatime
sets the last access time for a regular file to the current time.
This function should only be called by the stager after the file has been
successfully recalled and every time a stagein requests this file, even if
the file already resides in the disk pool.
The file can be identified by
.I path
name or by
.IR file_uniqueid .
If both are specified,
.I file_uniqueid
is used.
.TP
.I path
specifies the logical pathname relative to the current DPNS directory or
the full DPNS pathname.
.SH RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation
failed. In the latter case,
.B serrno
is set appropriately.
.SH ERRORS
.TP 1.3i
.B ENOENT
The named file does not exist or is a null pathname.
.TP
.B EACCES
Search permission is denied on a component of the
.IR path
prefix or the caller effective user ID does not match the owner ID of the file
or read permission on the file itself is denied.
.TP
.B EFAULT
.I path
and
.I file_uniqueid
are NULL pointers.

.B ENOTDIR
A component of
.I path
prefix is not a directory.
