4.3. How To Use the Automated Attendant Function Call

The li_attendant( ) API performs the actions of an automated attendant. This API operates in loop forever, synchronous mode and is designed to work in your application as a "created" thread.

To use this function in your application:

• You must provide the address of the li_attendant( ) as the entry point to the system call _beginthread( ). Do not use createthread( ).
• Before the li_attendant( ) thread can be created, your application must initialize a data structure providing information for the proper operation of the li_attendant( ) thread. This data structure, called DX_ATTENDANT, is described in the chapter on Data Structures.

To provide a way to terminate the li_attendant( ) thread, you must define a "named event" in the data structure. During the initialization process, the API verifies that the data structure contains valid entries. It checks for the presence of the named event. If the named event exists, li_attendant( ) continues and runs the automated attendant. If the named event does not exist, an error is returned. If the channel is on a non-STC board, li_attendant( ) terminates.

For more information on the synchronous programming model, refer to the Standard Runtime Library Programmer's Guide.
