Subject: rb_iterate

If anyone out there has used the "rb_iterate" function in a Ruby C
extension, could you please post a simple explanation of (a) how to
use the function and (b) an explanation of the method signature?

From eval.c ...

VALUE
rb_iterate(it_proc, data1, bl_proc, data2)
    VALUE (*it_proc) _((VALUE)), (*bl_proc)(ANYARGS);
    VALUE data1, data2;
{
    ...
}


I understand that "it_proc" and "bl_proc" are function pointers and
"data1" and "data2" are the arguments that are passed to each
function, respectively.  What I don't understand is how all these work
together to iterate over a collection.

Pointers, tips, tutorials, explanations?

Blessings,
TwP
