function hook_xmlrpc_alter

Alters the definition of XML-RPC methods before they are called.

This hook allows modules to modify the callback definition of declared XML-RPC methods, right before they are invoked by a client. Methods may be added, or existing methods may be altered.

Note that hook_xmlrpc() supports two distinct and incompatible formats to define a callback, so care must be taken when altering other methods.


$methods: An asssociative array of method callback definitions, as returned from hook_xmlrpc() implementations.
