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.
ERRORS
ENOENT The named file does not exist or is a null pathname.
EACCES Search permission is denied on a component of the 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.
EFAULT path and file_uniqueid are NULL pointers.
ENOTDIR A component of path prefix is not a directory.
EISDIR The file is not a regular file.
ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of
a path component exceeds CA_MAXNAMELEN.
SENOSHOST Host unknown.
SENOSSERV Service unknown.
SECOMERR Communication error.
ENSNACT Name server is not running or is being shutdown.
