*sigh* Another day, another inexplicable djgpp snafu. I wish I weren't
missing the docs, so I could easily find out what's been mis-installed
this time...

It's the GetMouseEvent() function from LIBGR.A. The problem is that it
seems to hang when I call it. I have some kind of three-button mouse,
plugged into I-don't-know-what-port (not a COM port though).


I wrote this source and saved it as MTEST.C, then compiled with

GCC MTEST.C -lpc -lgr -o MTEST.COF

then ran it with 

GO32 MTEST.COF

The clrscr() never executes and main() never ends. It appears that the
GetMouseEvent function isn't returning.



#include <stdio.h>
#include <conio.h>
#include <dos.h>
#include <mouse.h>


void main (void) {
  MouseEvent m;
  int f;
  MouseGetEvent(f, &m);
  clrscr();
}
