User Interface

The interface between the application programs and the ZCOM Subsystem is through the ZCOM 'C' Application Programming Interface (API) library. The functions provided by this library are documented in Chapter 4 “ZCOM C I/F Library Routines” All functions within the library are thread-safe and can be used in multi-threaded programs. Both 32-bit and 64-bit applications are supported.

The interactive program ZTERM gives the user access to all the ZCOM routines and can be used to test programs or terminals by sending and receiving messages between them. The program ZSCAN allows the programmer to display the contents of the ZCOM memory areas.
