# lfc\_setatime(3)

set last access time for a regular file to the current time

## NAME

lfc\_setatime - set last access time for a regular file to the current time

## SYNOPSIS

**#include \<sys/types.h\>**\
 **#include "lfc\_api.h"**

**int lfc\_setatime (const char \****path***,** **struct lfc\_fileid \****file\_uniqueid***)**

## DESCRIPTION

**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.

## 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.
