I left the details out to try to make it easy to see the main problem.
Anyway, here is the full prototype:
static void my_func (UInt16 *parm1,
UInt16 parm2,
Int16 rows,
Boolean parm4,
my_generic_func *parm5);
The actual invocation is like this:
my_func(&recno, count, number_of_rows, false, my_routine);
My declarations are:
typedef void my_generic_func (Boolean flag);
UInt16 recno;
UInt16 count;
Int16 number_of_rows;
All 3 of these global variables have the right values before the calls.
"RECNO" and "COUNT" are correct afterwards, only "NUMBER_OF_ROWS" seems to
get overwritten.
The "my_routine" function's prototype is:
static void my_routine (Boolean yesno);
Inside "my_func", the call looks like this:
parm5(true);
I didn't think it could have anything to do with these other parameters,
because it was working correctly on the release ROMS, but I certainly might
be wrong about that. Again, I get no errors or warnings regarding the stack
or anything else.
The main thing is this: The value is correct immediately before returning
from my_func, but INCORRECT immediately after the CALL to my_func. Something
(the stack?) is getting messed up as we return from the subroutine.
I hope these extra details help. Thanks!
Tom
