Hi,

I have a strange situation where running a program under a debugger
(RHIDE or GDB) will hang the debugger on the call to a particular
function. So I need to prevent calling this function when the program
is a debugee. How do I detect running under a debugger?

For the record, here is that function:

static inline void Wait (void)   /* wait until timer changes */
{
  unsigned long t = _farpeekl (_dos_ds,0x46C);
  while (_farpeekl(_dos_ds,0x46C) == t)
        ((void)0);
}


Gisle V.
