An app-supplied function for program entry.
Defined in <SDL3/SDL_main.h>
int SDL_main(int argc, char *argv[]);| int | argc | an ANSI-C style main function's argc. |
| char ** | argv | an ANSI-C style main function's argv. |
(int) Returns an ANSI-C main return code; generally 0 is considered successful program completion, and small non-zero values are considered errors.
Apps do not directly create this function; they should create a
standard ANSI-C main function instead. If SDL needs to
insert some startup code before main runs, or the platform
doesn't actually use a function called "main", SDL will do some
macro magic to redefine main to SDL_main and provide its own
main.
Apps should include SDL_main.h in the same file as their
main function, and they should not use that symbol for
anything else in that file, as it might get redefined.
This function is only provided by the app if it isn't using SDL_MAIN_USE_CALLBACKS.
Program startup is a surprisingly complex topic. Please see README-main-functions, (or docs/README-main-functions.md in the source tree) for a more detailed explanation.
This is the program entry point.
This function is available since SDL 3.2.0.
