char* description ( void   ) 

Provides a description of the module.

Returns:
a short description of your module

Definition at line 164 of file app_setcdruserfield.c.

00165 {
00166    return tdesc;
00167 }

char* key ( void   ) 

Returns the ASTERISK_GPL_KEY.

This returns the ASTERISK_GPL_KEY, signifiying that you agree to the terms of the GPL stated in the ASTERISK_GPL_KEY. Your module will not load if it does not return the EXACT message:

 char *key(void) {
         return ASTERISK_GPL_KEY;
 }

Returns:
ASTERISK_GPL_KEY

Definition at line 176 of file app_setcdruserfield.c.

References ASTERISK_GPL_KEY.

00177 {
00178    return ASTERISK_GPL_KEY;
00179 }

int load_module ( void   ) 

Initialize the module.

Initialize the Agents module. This function is being called by Asterisk when loading the module. Among other thing it registers applications, cli commands and reads the cofiguration file.

Returns:
int Always 0.

00121    return res;
00122 }

int unload_module ( void   ) 

Cleanup all module structures, sockets, etc.

This is called at exit. Any registrations and memory allocations need to be unregistered and free'd here. Nothing else will do these for you (until exit).

Returns:
Zero on success, or non-zero on error.

int usecount ( void   ) 

Provides a usecount.

This function will be called by various parts of asterisk. Basically, all it has to do is to return a usecount when called. You will need to maintain your usecount within the module somewhere. The usecount should be how many channels provided by this module are in use.

Returns:
The module's usecount.
