Before your application can utilize the interoperability functionality provided by the ToolTalk service and the Messaging Toolkit, it needs to know where the ToolTalk libraries and toolkit reside.
To use the ToolTalk service, an application calls ToolTalk functions from the ToolTalk API. The Messaging Toolkit provides functions such as functions to register with the ToolTalk service, to create message patterns, to send messages, to receive messages, and to examine message information. To modify your application to use the ToolTalk service and toolkit, you must include the appropriate header files in your application's .h file.
#include <Tt/tt_c.h> // ToolTalk Header File #include <Tt/tttk.h> // Messaging Toolkit Header file
Your application also needs to know about the new ToolTalk commands that are in its .c file. Place this information in your application's .h file, too.
Example 2-1 shows how the header file information is included in the CoEditor.h file.
#ifndef CoEditor_h #define CoEditor_h #include <X11/Intrinsic.h> #include <Tt/tt_c.h> // ToolTalk Header #include <Tt/tttk.h> // Messaging Toolkit Header
