ruby function calling c

[Justin Turney]

In this simple example, if I assign two Ruby functions to call the same
C function:

rb_define_method(m_rbTask, "prefix=", RUBYCAST(rb_prefix_set), 1);
rb_define_method(m_rbTask, "scratch=", RUBYCAST(rb_prefix_set), 1);

is there a way in rb_prefix_set to determine if the user used prefix= or
scratch=?

Thanks,
Justin

prefix= or

def my_caller
caller[0][/`(.*)'/, 1]
end

And use rb_funcall() to call my_caller.

See rb_frame_last_func().
