Returns the current position of the stack.
Integer_Type stk_current( Stack_Type stack )
This routine returns the current position within a stack.
This position determines the element returned by calls
to stk_read_next().
When a stack is created, the current position is set to 0
and it is increased by 1 each time stk_read_next()
is called. The position can also be changed by the skt_set_current()
and stk_rewind() functions.
if ( stk_current(stk) == stk_count(stk) ) stk_rewind(stk);
This code will reset the stack to its start position,
by calling stk_rewind(), if it has reached the end
of the stack.
