SDL and main

SDL Development
1

Hello all,

In the past, on smaller projects, I used to do the following:

#include <SDL/SDL.h> // which in turn includes SDLmain.h

#ifdef __cplusplus
extern “C”
{
#endif

int main(int argc, char **argv)
{
// blah
}

#ifdef __cplusplus
extern “C”
}
#endif

However, I now have a slightly larger project that has a bunch of libs (and
a main of course).
The libs that need SDL have the necessary includes, but my main is just

int main(int argc, char **argv)
{
// blah
}

without any of the SDLmain.h and extern “C” stuff.
Everything seems to be compiling and linking ok…Is SDLmain.h something I
always have to include with my
int main(int argc, char **argv)

What happens if I don’t?

Cheers,
Kos.

SDLmain provide a single and identical entry point in your program
(the main you provide) which can be something else on some other
platform (WinMain on win32 for example) -lSDLmain and SDLmain.h allow
you to use main on all platforms.On 11/23/06, Kostas Kostiadis wrote:
