function xmlrpc_example_xmlrpc

Implements hook_xmlrpc().

Provides Drupal with an array to map XML-RPC callbacks to existing functions. These functions may be defined in other modules. The example implementation defines specific functions for the example services.

Note: Drupal's built-in XML-RPC server already includes several methods by default:

Service dicovery methods:

• system.listMethods: return a list of the methods the server has, by name.
• system.methodSignature: return a description of the argument format a
• system.methodHelp: returns a text description of a particular method. particular method expects.

Other:

• system.multicall: perform several method calls in a single xmlrpc request.
• system.getCapabilities: determine if a given capability is supported.

The methods defined by hook_xmlrpc() will be added to those provided by default by Drupal's XML-RPC server.
