dpns_setatime(3) 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.
