MP_REGISTERPLUGIN(3MPAPI) Common Multipath Management Library Functions MP_REGISTERPLUGIN(3MPAPI)

MP_RegisterPlugin - register a plugin with the common library

cc [ flag... ] file... -lMPAPI [ library... ]
#include <mpapi.h>
MP_STATUS MP_RegisterPlugin(MP_WCHAR *pPluginId,
     MP_CHAR *pFileName);

pPluginId
A pointer to the key name shall be the reversed domain name of the vendor followed by a ".", followed by the vendor-specific name for the plugin that uniquely identifies it.

pFileName

The full path name of the plugin library.

The MP_RegisterPlugin() function registers a plugin with the common library. The current implementation adds an entry to the /etc/mpapi.conf file.

Unlike some other APIs, this API is implemented entirely in the common library. It must be called before a plugin is invoked by the common library.

This API does not impact dynamically add or change plugins bound to a running library instance. Instead, it causes an application that is currently not using a plugin to access the specified plugin on future calls to the common library. This is generally the behavior expected from dynamically loaded modules.

This API is typically called by a plugin's installation software to inform the common library of the path for the plugin library.

It is not an error to re-register a plugin. However, a plugin has only one registration. The first call to deregister a plugin will deregister it no matter how many calls to register the plugin have been made.

A vendor may register multiple plugins by using separate plugin IDs and filenames.

MP_STATUS_INVALID_PARAMETER

The pFileName does not exist.

MP_STATUS_SUCCESS

The operation is successful.
