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.
