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.

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.
