Thanks Jan, you have been a great help..how do I set the stack pragma to
compile these critical functions?
...I found a way to somewhat resolve the problem. I have 3 fairly large
structs (about 60 variables). When I try to store all the data in one
form, thats when it gives me the stack overflow error. So I created
another save form and stored data to 2 of the large structs there, and it
didnt give me the error. However, it's still giving me a warning saying
that I am 'close' to overflowing the stack, but the program is still
running fine on the palm device....I would still like to know how to check
for functions that are overflowing the stack however for my own knowledge.
I've never really tried to debug in a low source level.
What is the stack impact of these struct's ??
Are you doing:
struct FIELD_DEF {...} fields; /// wrong!!! , uses stack
or
struct FIELD_DEF (...) *pfields = NULL; // stack impact is 4 bytes
pfields = (struct FIELD_DEF *)
MemPtrNew (sizeof (struct FIELD_DEF) + 2);
if (pfields == NULL) { /* handle memory error */ return -1;}
MemSet ((MemPtr)pfields, sizeof (struct FIELD_DEF) + 2, 0);
// Note defensive programming techniques
...
...
...
MemPtrFree ((MemPtr)pfields; pfields = NULL;
return 1;
