int lfc_setatime (const char *path, struct lfc_fileid *file_uniqueid)
lfc_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 LFC directory or the full LFC pathname.
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
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.
