Detailed Description

App to set callerid.

Function Documentation

char* description ( void   ) 

Provides a description of the module.

Returns:
a short description of your module

Definition at line 163 of file app_setcallerid.c.

00164 {
00165    return tdesc;
00166 }

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 175 of file app_setcallerid.c.

References ASTERISK_GPL_KEY.

00176 {
00177    return ASTERISK_GPL_KEY;
00178 }

int load_module ( void   ) 

Initialize the module.

This function is called at module load time. Put all code in here that needs to set up your module's hardware, software, registrations, etc.

Returns:
This function should return 0 on success and non-zero on failure. If the module is not loaded successfully, Asterisk will call its unload_module() function.
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.

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.
