Abandon a variable argument list

     #include <varargs.h>
     va_end(va_list AP);
Use `va_end' to declare that your program will not use the variable
argument list AP any further.
`va_end' does not return a result.
The `va_end' defined in `varargs.h' has the same syntax and usage as
the ANSI C version from `stdarg.h'.
