Yes, your assumption is correct. I goofed. I had typed in the first Extern declaration and then copied and pasted it three 
times. I changed the Gambas function name on those three but not the library's function name. Good catch.

It's good to see that you successfully implemented a different external function call. You see that it /can/ be quite simple. It 
will get more complex when you need to use pointers.

One thing to keep in mind, for future reference, is that Gambas can interface only with libraries written in C and not in C++ 
(unless the library does not use any C++ structures or capabilities that are not C compatible). If there is a particular library 
with which you'd like to interface and it is written in C++, look to see if it has a C-wrapper.


If you have any questions, feel free to ask here. Have fun!
