Detailed Description

SayUnixTime application.

Definition in file app_sayunixtime.c.


Function Documentation

char* description void   ) 
 

Provides a description of the module.

Returns:
a short description of your module

Definition at line 148 of file app_sayunixtime.c.

00149 {
00150    return tdesc;
00151 }

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 160 of file app_sayunixtime.c.

00161 {
00162    return ASTERISK_GPL_KEY;
00163 }

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.

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.
