stackavail()             Return Size of Available Stack Memory
 
 #include   <malloc.h>                   Required for declarations only
 
 unsigned   int stackavail(void);
 
    stackavail() returns the approximate number of bytes on the stack
    available for allocation.  They can be allocated by using alloca().
 
    Returns:    Approximate number of bytes available on the stack.
 
  -------------------------------- Example ---------------------------------
 
    The following statement reports the approximate number of bytes
    available for allocation on the stack:
 
            #include <malloc.h>
            #include <stdio.h>      /* for printf */
 
            main()
            {
                printf("%u bytes of stack space available\n",
                       stackavail());
            }
