Why?
Thanks

Is there a similar keyword to declare calling convention?

Yes I expect so, but you will have to look in the compiler documentation to find it.

Solution 1

__stdcall is Microsoft specific so will not be part of the standard language accepted by the gcc/g++ compiler.

If you're using the MinGW port of gcc there's probably a stdcall implementation for calling windows API functions. However you'll have to look in the gcc docs to find out what it is (or look in the MingGW windows.h and see how it decorates windows API function prototypes).

If you're not using MinGW (or one of the other Windows ports of gcc) then there's no need to use stdcall - the default calling convention is probably okay for anything you'd want to do.

Cheers,
