Hi everybody,


I'm working on an extension to ruby that will allow me to work directly with
Orca (a dll that allows you to work directly with pbls - Powerbuilder
libraries). I'm not familiar with the ruby API's and I have some problems
(like documentation I'm using "Programming Ruby").


Then:

How can I know the size of an ruby array?

STR2CSTR makes a copy? Or gets only a pointer to?

If I want to pass to a function a pointer array of C strings and the strings
are in a ruby array of strings, how can I do??



TIA,

Andy Neagu
