Replacing WinMain() with main() function in Win32 programs

by

You can use standard main in a “windows” app (that is, a GUI subsystem Windows application) even with the Microsoft tools, if you add the following to the Microsoft linker options:

/subsystem:windows /ENTRY:mainCRTStartup

Note that this is not necessary for the GNU toolchain.

Still for the Microsoft tools you can alternatively add this to your main file:

#ifdef _MSC_VER
#    pragma comment(linker, "/subsystem:windows /ENTRY:mainCRTStartup")
#endif

James McNellis tells you how to get the hInstance.
