import C functions

[Kitty Hello]

GLBasic can now include native C functions and files w/o INLINE:

Main.gbas file

Code (glbasic) Select Expand



REQUIRE "test1.cpp" // advise the compiler to take a cpp file, too

IMPORT "C" int Muh(); // IMPORT is like "extern" in C++. All the rest is the same.

Muh() // call it


test1.cpp

Code (glbasic) Select Expand


#include "glb.h"

extern "C" int Muh()
{
STDOUT("Muh!");
}

cooooooooool!

Excellent Gernot, thank you, could we have a mini tutorial please specifying...

• What variable types can be used within GLBasic
• How pointers are dealt with?
• Is it possible to pass C structures, if so, how is this used within GLBasic?
• Anything else regarding passing data back and forth

Overall a big  from me!

really good news! top!

@bigsofty
let's try it out I hope it's possible to use class definitions within the cpp files

[MrTAToad]

It'll make things easier

[Kitty Hello]

no structure passing. Make that inline or a wrapper. type conversion is:

int, long, short, char, void* -> DGNat
double, float -> DGInt
int& -> DGNat BYREF
double& -> DGInt BYREF
char*, const char* -> DGStr

[Quentin]

is this feature ready for download in Beta Release?

Ooooh I like INLINE though!

I like this idea a lot too though.   Definitely a cool feature.

[Hatonastick]

Ooooh I like INLINE though!

it's not mutually exclusive, so.... 

Darn, so there's no point ranting, raving and demanding it be put back the way it was then?

That IMPORT-Functions need to highlight on the IDE...( and Autocompletion/ see the parameters on the "tooltip" at the bottom of the IDE)

Gernot, realy good work!
I can create my "Menu wrapper" from windows.h with that. (without a DLL and YES i can include <windows.h>... but <iostream> crashs)
Works fine

The line, which IMPORT is written on, is highlighted blue, with the new black theme.

But the declaration itself(IMPORT), and the declared command words are not highlighted.

Question: This new command import, is it the same thing as setting up an inline?

[MrTAToad]

Import allows access to the function included by Require - its somewhat like Declare.

Whoops missed this reply, thanks Gernot!
