Bear in mind this is a declaration for a function that returns a function pointer. In other words you are meant to call the return value as a function.

It would look something like this:

I'm not sure what you mean about "free for real." When you use FB delete, memory is released--it *is* freed for real. The pointers that may have pointed to the memory have nothing to do with that. The OS can't help it if you try to refer to some memory that you shouldn't be. FB is not Free...

You're the programmer. You are the one who knows whether a pointer is "clean" or not. If you can't always make that clear, assign a NULL to the pointer after you delete the memory. I don't see any problem or "mess" with with FB. Having the language set pointers to NULL isn't some...

mark, are you using Linux? superuser should not be required to access a serial port in Linux. Instead you need to make your normal user a part of the built-in "dialout" group. Once you do that, then you can access serial ports as a normal user. Most linux distributions have GUI tools for m...

Another good remote desktop solution you can use with the pi is X2Go. It's based on some of the same technologies as NoMachine is, but is in the Rasbian default software respository so it's an easy install.

It's not necessary to be root to access serial ports. Nearly all modern Linux distros have a group called, somewhat anachronistically, "dialout" and all serial devices are by default set to be group read and write-able to that group ip. So you just need to add your user id to that group an...

Are you wanting to make the animations be interactive? In other words are you trying to turn your FB programs into web-based programs that take user input from the web page and generate the appropriate animation? Or are you just wanting to capture the animations and re-play them back in a web page? ...

Using the code example below I get this error? blinkLedRpi.bas(18) error 42: Variable not declared, outout in 'open "/sys/class/gpio/gpio29/value" for outout as #hFile' Looking closely at that error message, the problem is that you spelled output wrong (outout). But that is a bit weird of...

Is there a link to sample code embedding Tcl/Tk in Freebasic program? Not that I know of. Also I don't know of any FreeBASIC translations of the Tcl C header files, so you'd have to translate them into .bi files yourself, or at least translate enough of them to access the C api. This is what I trie...

Can Tk be used from Freebasic? Yes it could, just as you can use Tk from C. But you'd need to translate the C header files into FB .bi files for the Tcl C API library. Basically you'd be embedding the Tcl interpreter inside your FB program, and then using the C API to interact with it, and to inter...

Since when is WIN-API cross platform (WIN & LIN)? Natively, without WINE, that is. Well technically wine let's you compile win32 C (and C++) source code to native linux binaries using what they call winelib. The result is an elf executable and a few shared libraries. In fact you can even use wi...

FB is a language that implements variables as boxes in memory that you can address, so I would expect a deep copy in FB, and that appears to be what happens. Python is more abstract and its variables do not work the same way. Also I notice in python (lists) that it seems to be a pointer copy also. T...

Zlib uses the "deflate" compression algorithm, which is actually a combination of a couple of different common compression algorithms. It's well documented if you wish to learn more about it.

Correct. ctypes is, in Python 3 at least, a built-in module. Python 3 is definitely faster than Python 2. If you're trying to do a lot of intensive math calculations in Python, you will be disappointed compared to compiled FB performance. However in the scientific and math community Python is often ...

The final alternative is to create a Python function using the C API and have that function pass data between FB and Python. See https://stackoverflow.com/questions/13942128/how-to-pass-an-array-from-c-to-an-embedded-python-script. The SOF article speaks only about passing data to Python. You might...
