qthread_stackleft - returns the amount of space left in the thread’s
allocated stack
#include <qthread/qthread.h>
size_t
qthread_stackleft(qthread_t *t);
This function returns the number
of bytes left in the stack. The argument, t, MUST be the current qthread
for the answer to make sense.
This function is intended primarily for debugging,
and the answer is often imprecise and unreliable.
If t is non-null,
it returns the number of bytes left in the stack, accurate to a small margin
(on the order of 10 bytes). If t is NULL, qthread_stackleft() returns 0.
