c - how to analysis this excerpt of Ruby source code about === method -


i found example , metaphor of object#=== operatorare confusing, i'm begin read source code, i'm new c, tell me how analysis code:

value rb_equal(value obj1, value obj2) {     value result;      if (obj1 == obj2) return qtrue;     result = rb_funcall(obj1, id_eq, 1, obj2);     if (rtest(result)) return qtrue;     return qfalse; }

value generic type of ruby objects in c (as opposed c types int). can deduce rb_equal function comparing 2 ruby objects (obj1 , obj2). if 2 objects equal qtrue (the represantion of ruby's true in c) returned. if not rb_funcall call equality method (id_eq) on obj1. if result truthy (checked rtest(result)) qtrue returned. if hit end of function 2 objects not same, we'll return false (qfalse).
