| ** XML-RPC Server Method Registry |
| **========================================================================= |
| ** A method registry maintains a list of functions, and handles |
| ** dispatching. To build an XML-RPC server, just add an XML-RPC protocol |
| ** driver. |
| ** |
| ** Methods are C functions which take some combination of the following |
| ** parameters. All pointers except user_data belong to the library, and |
| ** must not be freed by the callback or used after the callback returns. |
| ** |
| ** env: An XML-RPC error-handling environment. No faults will be |
| ** set when the function is called. If an error occurs, |
| ** set an appropriate fault and return NULL. (If a fault is |
| ** set, the NULL return value will be enforced!) |
| ** host: The 'Host:' header passed by the XML-RPC client, or NULL, |
| ** if no 'Host:' header has been provided. |
| ** method_name: The name used to call this method. |
| ** user_data: The user_data used to register this method. |
| ** param_array: The parameters passed to this function, stored in an |
| ** XML-RPC array. You are *not* responsible for calling |
| ** xmlrpc_DECREF on this array. |
| ** |
| ** Return value: If no fault has been set, the function must return a |
| ** valid xmlrpc_value. This will be serialized, returned |
| ** to the caller, and xmlrpc_DECREF'd. |
| */ |
