.SH NAME
|
|
.BR _beginStackCheck ,
|
|
.BR _endStackCheck
|
|
\- report stack usage
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <gno/gno.h>
|
|
|
|
void _beginStackCheck(void);
|
|
int _endStackCheck(void);
|
|
.nf
|
|
.SH DESCRIPTION
|
|
These routines are intended to determine the required stack usage
|
|
for a program during the development cycle.
|
|
.LP
|
|
.BR _beginStackCheck
|
|
should be called as soon as possible after the program starts.
|
|
.BR _endStackCheck
|
|
should be called just prior to program exit.
|
|
.BR _endStackCheck
|
|
will return the number of bytes of stack space used by the program. The
|
|
result can then be used as a
|
|
.I lower
|
|
bound for the argument to
|
|
.BR occ 's
|
|
.BR -s
|
|
flag, or the
|
|
.I stacksize
|
|
pragma for Orca/C.
|
|
.SH EXAMPLE
|
|
An easy way to use these set of routines is to make use of the
|
|
.BR atexit (3)
|
|
function, so that you don't have to determine all the possible exit
|
|
points of your program.
|
|
.nf
|
|
|
|
#include <stdio.h>
|
|
#include <gno/gno.h>
|
|
|
|
void cleanup (void) {
|
|
fprintf(stderr,"Stack Usage: %d bytes\n", _endStackCheck());
|
|
}
|
|
|
|
void main (int argc, char **argv) {
|
|
|
|
_beginStackCheck();
|
|
atexit(cleanup);
|
|
|
|
... <program continues> ...

|
|
and
