You might want to try using one of the LIBraries, or compile MSGAPI
yourself.  Many libraries and source code is included with the Squish
Developers Kit.  I couldn't figure out how to use the MSGAPI.DLL  Then
again, I guess you can't use OS/2 DLLs in Windows and vice-versa.  :(

Good Luck!  The headers for Squish are complex.  It is best to learn C
again to use the msgapi.  However, there is documentation that describes in
detail the structure layout of the Squish format and how to access it.  In
the SQDEV documenation, it says you may need to access it directly and not
through the MSGAPI since the API was intended for C.

   MsgApiRes = InitMsgApi(DefaultFidonetZone);

   {
      printf("MsgApiInit failure.\n");
      return 0; 
   }
   printf("MsgApiInit success.\n");
   (void) TerminateMsgapi();
   return 0;
}

int InitMsgApi(int DefaultZone)
{
  struct _minf minf;

  minf.req_version = 1; /* the required msgapi version for your program */
  minf.def_zone    = DefaultZone;
                /* default fidonet zone */
  /* minf.haveshare   = 1; You do not assign haveshare */

/*  These are function pointers to memory functions you care to use

  minf.palloc      = 0x0L;
  minf.pfree       = 0x0L;
  minf.repalloc    = 0x0L;
  minf.farpalloc   = 0x0L;
  minf.farpfree    = 0x0L;
  minf.farrepalloc = 0x0L;

  return MsgOpenApi(&minf);
}

int TerminateMsgApi(void)
{
  return MsgCloseApi();
}
