PA_CheckFreeStack

version 2003

PA_CheckFreeStack (request) → Long

The routine PA_CheckFreeStack checks to see if the current process' stack can hold the amount of stack passed in request and returns the amount of stack available. If you want to know the amount of available stack, pass 0 as the requested stack.

It the stack cannot hold the amount passed in request, 4D displays an alert ("The stack is full").

Check if there enough stack to launch a method without displaying an alert.

   char HaveEnoughStack(long amount)
   {
      return (char) (PA_CheckFreeStack(O) >= amount) ? 1 : 0;
   }

No reference.

Use PA_GetLastError to see if an error occurred ( eER_StackIsFull ).
