| isFunction |
(Object obj [, int count]) |
yoix.type |
| |
Returns
1
if
obj
is a
Function
and
0
otherwise.
If the optional
count
argument is supplied the return value will only be
1
if
obj
is a
Function
that accepts
count
arguments.
| |
| Example: |
A
NULL
object that was declared to be a
Function
can be called with zero arguments, so the program
import yoix.*.*;
Function f;
Object o;
printf("f=%O, isFunction(f)=%d\n", f, isFunction(f));
printf("o=%O, isFunction(o)=%d\n", o, isFunction(o));
prints
f=NULL:FUNCTION, isFunction(f)=1
o=NULL:OBJECT, isFunction(o)=0
on standard output.
