I will pass it to my friend who will code in C for us. However - how should
I put Rebol string datatype into array of unsigned values??? I don't want to
taky any time consuming operation in Rebol, as that's exactly the reason why
I want to call library function - the speed ...
The simple question once again :-) - Is string sent to library interface
being automatically ended once "0" char appears in it? (and vice versa - the
same for string returning from library interface to Rebol?)
Thanks,
