# dpns\_listrep4gc(3)

list replica entries that can be garbage collected

## NAME

dpns\_listrep4gc - list replica entries that can be garbage collected

## SYNOPSIS

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

**struct dpns\_filereplicax \*dpns\_listrep4gc (const char \****poolname***,** **int** *flags***,** **dpns\_list \****listp***)**

## DESCRIPTION

**dpns\_listrep4gc** lists replica entries that can be garbage collected.

- *poolname*

  specifies the disk pool.

- *flags*

  may be one of the following constant:

  - **CNS\_LIST\_BEGIN**

    the first call must have this flag set to allocate buffers and initialize pointers.

  - **CNS\_LIST\_CONTINUE**

    all the following calls must have this flag set.

  - **CNS\_LIST\_END**

    final call to terminate the list and free resources.

## RETURN VALUE

This routine returns a pointer to a structure containing the current replica entry if the operation was successful or NULL if all entries have been returned or if the operation failed. In the latter case, **serrno** is set appropriately.

## ERRORS

- **ENOMEM**

  Memory could not be allocated for the output buffer.

- **EFAULT**

  *poolname* or *listp* is a NULL pointer.

- **EINVAL**

  The length of *poolname* exceeds **CA\_MAXPOOLNAMELEN**.

- **SENOSHOST**

  Host unknown.

- **SENOSSERV**

  Service unknown.

- **SECOMERR**

  Communication error.

- **ENSNACT**

  Name server is not running or is being shutdown.
