what's the correct way to do this? i'm poking around in file.c now - no
File.new to be found... IO.open perhaps? i need to return an open file from
a c function...
cheers.

This should work:
return rb_funcall(rb_cFile, rb_intern(":new"), rb_str_new2("filename"));

Hmmm...do you want MakeOpenFile() from rubyio.h?

You should see io.c.
VALUE rb_file_open(const char *fname, const char *mode);
VALUE rb_file_sysopen(const char *fname, int flags, int mode);
Hmmm, but rb_file_sysopen() lacks the prototype...

Oops, try:
return rb_funcall(rb_cFile, rb_intern(":new"), 1, rb_str_new2("filename"));

bingo. that solve's problem one.
problem two - correct way for turning a FILE *filep into a rb_cFile;

return rb_funcall(rb_cFile, rb_intern(":new"), 1, rb_str_new2("filename"));
rb_intern(":new") differs from rb_intern("new").
You also can use rb_class_new_instance() instead.
return rb_class_new_instance(1, rb_str_new2("filename"), rb_cFile);

hmmm. is this really the best way? i mean, why not call the dispatched to
method directly? i suppose this insulates you from name changes - but it
seems like one should be to call it directly doesn't it?
cheers.

Since in C you don't have access to all of the C functions that implement
every method in every class, it's simply the most consistent way to make the
call. If you know the actual C function name, I'm sure you could call that
directly.
