That won't do it.

The stack is different from CLI and Workbench.  If your compiler has
a global that gives the stack size, then use it.  Else:

/*
 * stack_test.c  27-Oct-87.  Bryce Nesbitt
 *
 */
#include "exec/types.h"
#include "exec/tasks.h"
#include "libraries/dosextens.h"
#include "stdio.h"
struct Process *FindTask();

void main()
{
register struct Process     *Process;
register FILE		    *Handle;
struct CommandLineInterface *CLI;

    if (!(Handle=fopen("con:0/11/250/128/Stack Window","a")))
	exit(20);       /* "a" is used so the window won't flicker */

    Process=FindTask(0L);

    if (CLI=(struct CommandLineInterface *)(Process->pr_CLI<<2))
	{
	if (CLI->cli_Background)
	    fprintf(Handle,"Background");
	else
	    fprintf(Handle,"Foreground");
	fprintf(Handle," CLI #%ld\n",Process->pr_TaskNum);

	fprintf(Handle,"Actual stack is: %ld\n\n",
	       CLI->cli_DefaultStack<<2);
	}
    else
	{
	fprintf(Handle,"This is not a CLI process\n");
	fprintf(Handle,"Actual stack is %ld\n\n",Process->pr_StackSize);
	}
    Delay(100L);    /* Be quick :-).  BTW: *Never* Delay(0L);! */
    fprintf(Handle,"\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n");
		    /* Dramatic exit :-) */
    fclose(Handle);
}
