Thanks, I worked out my issue was I was passing a null pointer to the memory function and then calling my external function. The error I kept getting was a type mismatch and did not make sense to me as the docs led me to believe that the Memory steam was a declaration, not a function on an actual pointer.
It was late here and I may have misread the docs. A sample in the documentation would be great as well as adding a note to the page on using external libraries on how to Read and write to memory streams from Gambas 3. That document has other note about using Gambas 3 but does not mention that Gambas 3 can no longer use pointers to read from memory as the example shows. I only found that information while reading through the stream documentation. Thank you for your response!
