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

- SENOSSERV
- Service unknown.
