[Gambas-user] error calling external function from c library

[Marcos Antonio Pandolfo Jr]

Hi Everybody

Well, I resolv my problem !!!!!!

I realized that there is one more variable in this function that should be a
pointer.... And the lenght of this pointer must be informed in the call of
function.....

So... Thanks so much for the help and congratulations to everyone....

Abraços

Marcos Pandolfo Jr
