| Platform SDK: TAPI |
All service providers must implement Basic Telephony functions. The following is a list of such functions by category. A function is identified as asynchronous if it indicates completion in a REPLY message to the application. If the function always returns its result immediately, the function is considered synchronous.
Opening and Closing Line Devices
