NAME¶

SDL_RunApp - Initializes and launches an SDL application, by doing platform-specific initialization before calling your mainFunction and cleanups after it returns, if that is needed for a specific platform, otherwise it just calls mainFunction.

SYNOPSIS¶

#include "SDL3/SDL.h"

int SDL_RunApp(int argc, char* argv[], SDL_main_func mainFunction, void * reserved);

DESCRIPTION¶

You can use this if you want to use your own main() implementation without using SDL_main
(like when using

SDL_MAIN_HANDLED ). When using this, you do not need

SDL_SetMainReady ().

FUNCTION PARAMETERS¶

argc

The argc parameter from the application's main() function, or 0 if the platform's main-equivalent has no argc

argv

The argv parameter from the application's main() function, or NULL if the platform's main-equivalent has no argv

mainFunction

Your SDL app's C-style main(), an SDL_main_func . NOT the function you're calling this from! Its name doesn't matter, but its signature must be like int my_main(int argc, char* argv[])

reserved

should be NULL (reserved for future use, will probably be platform-specific then)

RETURN VALUE¶

Returns the return value from mainFunction: 0 on success, -1 on failure;

SDL_GetError () might have more information on the failure

AVAILABILITY¶

This function is available since SDL 3.0.0.
