7       time

SYNOPSIS

10       #include <sys/types.h>
11       #include "dpns_api.h"
12
13       int dpns_setatime (const char *path, struct dpns_fileid *file_uniqueid)
14

DESCRIPTION

16       dpns_setatime sets the last access time for a regular file to the  cur‐
17       rent time.  This function should only be called by the stager after the
18       file has been successfully recalled and every time a  stagein  requests
19       this file, even if the file already resides in the disk pool.  The file
20       can be identified by path name or by file_uniqueid.  If both are speci‐
21       fied, file_uniqueid is used.
22
23       path   specifies  the  logical  pathname  relative  to the current DPNS
24              directory or the full DPNS pathname.
25

RETURN VALUE

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