int ast_module_reload ( const char *  name  ) 

Reload asterisk modules.

Parameters:
name the name of the module to reload
This function reloads the specified module, or if no modules are specified, it will reload all loaded modules.

Note:
Modules are reloaded using their reload() functions, not unloading them and loading them again.
Returns:
0 if the specified module was not found.
Return values:
1 if the module was found but cannot be reloaded.
-1 if a reload operation is already in progress.
2 if the specfied module was found and reloaded.

void ast_process_pending_reloads ( void   ) 

Process reload requests received during startup.

This function requests that the loader execute the pending reload requests that were queued during server startup.

Note:
This function will do nothing if the server has not completely started up. Once called, the reload queue is emptied, and further invocations will have no affect.
