# lfc\_setfsizeg(3)

set filesize for a regular file having the given GUID; set also last modification time to the current time

## NAME

lfc\_setfsizeg - set filesize for a regular file having the given GUID; set also last modification time to the current time

## SYNOPSIS

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

**int lfc\_setfsizeg (const char \****guid***,** **u\_signed64** *filesize***,** **const char \****csumtype***,** **char \****csumvalue***)**

## DESCRIPTION

**lfc\_setfsizeg** sets the filesize for a regular file having the given GUID; set also the last modification time to the current time. This function should only be called by the stager after the last write operation has been performed on the file. The file is identified by its *guid*.

- *guid*

  specifies the Grid Unique IDentifier.

- *csumtype*

  specifies the type of checksum. Valid types are:

  - **CS**

    standard 32 bits checksum

  - **AD**

    Adler 32 bits checksum

  - **MD**

    MD5 128 bits checksum

## 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

- **EFAULT**

  *guid* is a NULL pointer.

- **EINVAL**

  The length of the *guid* exceeds **CA\_MAXGUIDLEN** or the length of the *csumtype* exceeds 2 or *csumtype* is an unknown type or the length of the *csumvalue* exceeds 32.

- **SENOSHOST**

  Host unknown.

- **SENOSSERV**

  Service unknown.

- **SECOMERR**

  Communication error.

- **ENSNACT**

  Name server is not running or is being shutdown.
