[Gambas-user] Working with .so library

[Admin]

BTW, can Gambas point to an array? I mean, there's datatype in C called 
bytearray, and some of my .so library's procedures return or request a 
bytearray variable. Gambas can declare a Byte[] but can't VarPtr to it. 
So that's a no, right? Just making sure, it's not that important, but 
maybe there's a way?
