5.1 Main Program

This chapter describes how the functions defined in DM are realized in C and how they have to be linked to DM.

In principle each C program having the name "AppMain" in the non-distributed version has the name "AppInit" in the distributed version.

This main program is called by the Dialog Manager and can then carry out the necessary initialization steps.

5.1.1 Local C Programs

In the local version of Dialog Manager the program "AppMain" in principle is the virtual program. It has to carry out the following steps:

• initialization of Dialog Manager (DM_Initialize)
• loading a dialog (DM_LoadDialog)
• initialization of application
• passing on the function addresses (DM_BindFunctions)
• reading in the user profile (DM_LoadProfile)
• starting the dialog (DM_StartDialog)
• starting the processing (DM_EventLoop)

After having carried out these steps successfully, you can work with the program.

5.1.2 Distributed C Programs

In the distributed version of Dialog Manager the C main program "AppInit" has to carry out the following steps:

• passing on function addresses (DM_BindFunctions)
• initialization of application.
