LHAPI Initialization

A LHAPI application is also a System Manager application. First, a LHAPI app must register itself as a System Manager application, then register itself as a LHAPI application. The two are very distinct, and although you can have a System Manager application without LHAPI, you cannot have a LHAPI application without the System Manager. Here is a typical initialization:

//Register ourself with the System Manager:

     m_init_app(SYSTEM_MANAGER_VERSION); 

//Register our application's name (the user will see this):

     m_reg_app_name("My Test App"); 

//Register our far pointer table (in case we need to make dynamic memory allocations:

     #define countof(x) (sizeof(x)/sizeof(x[0])) 

     char far *SysMgrFarPtrs[10]; 

     m_reg_far(&SysMgrFarPtrs, countof(SysMgrFarPtrs), 0); 

     Next, any initialization required for LHAPI should be done.  

//Register our application with LHAPI.

     LHAPIBLOCK LHAPIData; 

     InitializeLHAPI(&LHAPIData); 

//Set the default font and the menu font to 64x18

     SetMenuFont(FONT_NORMAL); 

     SetFont(FONT_NORMAL);
