Hello All!


Is there anyone out there that can give me some help to get started using
MSGAPI32.DLL from Pascal?

I have the archive SQDEV200.ZIP which has all necessary headers to use
MSGAPI32.DLL in C programs. The problem is that I am not confident with C,
and haven't used it since 1986.

To use this .DLL from Pascal, I suppose one will have to translate some .h
files (at least MSGAPI.H) - but that should be no problem.

The biggest problem is how to call the .DLL functions from within a Pascal
program. Could anyone help me to write a small sample program showing this
crucial part?

The simplest possible program using MSGAPI would be something like:

  * Calling MsgOpenApi
  * Calling MsgCloseApi

C Definitions:

       sword MsgOpenApi(struct _minf *minf);
       sword MsgCloseApi(void);

       struct _minf
       {
           word req_version;
           word def_zone;
           word haveshare;

           void OS2FAR * (MAPIENTRY *palloc)(size_t size);
           void (MAPIENTRY *pfree)(void OS2FAR *ptr);
           void OS2FAR * (MAPIENTRY *repalloc)(void OS2FAR *ptr, size_t size);

           void far * (MAPIENTRY *farpalloc)(size_t size);
           void (MAPIENTRY *farpfree)(void far *ptr);
           void far * (MAPIENTRY *farrepalloc)(void far *ptr, size size);
       };

Concerning which Pascal compiler to use, either Speed Pascal or Virtual
Pascal will do.


regards,
        David
