Subj : Iterating through all Array elements from C

Using SpiderMonkey, I have a static function of a class which requires
an array as a parameter.  I can get the parameter, verify that it is
indeed an Array...  However, I seem to have trouble to iterate though
all its elements, if the indexes are either non-contiguous or
non-numeric at initialization:

Works:

fdset[0] = fd1;
fdset[1] = fd2;
....

Works:

fdset.push(fd1);
fdset.push(fd2);
....

Fails:

fdset[0] = fd1;
fdset[2] = fd2;

Fails:

fdset['input'] = fd1;
fdset['output'] = fd2;


This is using JS_GetArrayLength(), and iterating through 0 to its
returned value using JS_GetElement().  Is there another way I can use
for all types of arrays to work without straying off too much of the
standard API?  (non-contiguous elements ones, and associative ones).

Thanks,
Matt
