Help Structures

typedef struct HELPSTRUCT { 
          unsigned int  wSize;      /* Struct size: For compatibility check */ 
          char *        pHelpFile;  /* Near ptr to path and name of Help file */ 
          char *        pHelpData;  /* Near ptr to far ptr to Help data area */ 
          unsigned int  wHelpRev;   /* Help file rev #: compatibility check */ 
          char *        pKeyTxt;    /* Near ptr to Bottom Row key text */ 
} HELPSTRUCT;

pHelpFile is a near pointer to a null terminated file name string (with extension) in the default Data segment. The name must not contain the country code since the Help System will insert it during initialization, for example LHTEST.HLP would be converted to LHTESTUS.HLP.

pHelpData is a near pointer to a far pointer to an area of RAM, of size HELPDATASIZE. This indirection scheme is being used to take advantage of the System Manager Memory Management Services.
