All modules must have at least the following functions:
|
|
|
|
int load_module():
|
|
|
|
Do what you need to do when you get started. This function
|
|
returns 0 on success and non-zero on failure (it is not considered loaded
|
|
if it fails.
|
|
|
|
int unload_module():
|
|
|
|
The module will soon be unloaded. If any channels are using your
|
|
features, you should give them a softhangup in an effort to keep the
|
|
program from crashing. Generally, unload_module is only called when the
|
|
usecount is 0 or less, but the user can force unloading at their
|
|
discretion, and thus a module should do its best to comply (although in
|
|
some cases there may be no way to avoid a crash). This function should
|
|
return 0 on success and non-zero on failure (i.e. it cannot yet be
|
|
unloaded).
|
|
|
|
char *description():
|
|
|
|
Return a description of the module's functionality.
|
|
|
|
int usecnt():
|
|
|
|
Return the number of channels, etc that are using you.
