SDL_RunApp - Man Page
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_main.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(). NOT the function you're calling this from! Its name doesn't matter; it doesn't literally have to be main.
- 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, otherwise failure; SDL_GetError() might have more information on the failure.
Thread Safety
Generally this is called once, near startup, from the process's initial thread.
Availability
This function is available since SDL 3.2.0.
