NAME

       dpns_setatime - set last access time for a regular file to the current time

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       int dpns_setatime (const char *path, struct dpns_fileid *file_uniqueid)

DESCRIPTION

       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
       path name or by file_uniqueid.  If both are specified, file_uniqueid is used.

       path   specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case,
       serrno is set appropriately.
