SDL_SCANF_FORMAT_STRING(3)

πŸ’– SDL_SCANF_FORMAT_STRING πŸ’–

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, we're doing SDL_SCANF_FORMAT_STRING(3) today and it's honestly such a small slay πŸŽ€


✨ NAME ✨

SDL_SCANF_FORMAT_STRING β€” the macro that annotates function params as scanf-style format strings. that's it, that's the whole job πŸ’…


🌸 SYNOPSIS 🌸

#include <SDL3/SDL_stdinc.h>

#define SDL_SCANF_FORMAT_STRING _Scanf_format_string_impl_

πŸ¦‹ DESCRIPTION πŸ¦‹

so picture this: you wanna annotate fscanf. like, hypothetically. here's what that would look like:

int fscanf(FILE *f, SDL_SCANF_FORMAT_STRING const char *fmt, ...);

see how fmt is wearing the SDL_SCANF_FORMAT_STRING fit? that's the whole point. it notes that fmt should be a scanf-style format string. and then the compiler β€” or whatever other analysis tools you've got lurking in your build pipeline πŸ‘€ β€” can warn you when it doesn't actually appear to be the case. vibe check on your format string, basically. πŸ”₯

and if you're on compilers that just don't have this annotation mechanism? no worries bestie, on those this is defined to nothing. literally nothing. it just vanishes. iconically low-maintenance. πŸ’€


⭐ AVAILABILITY ⭐

this macro is available since SDL 3.2.0. so if you're on something older, sorry babes, upgrade time 🫢


quick reminder: this is an annotation macro, not a function β€” it does absolutely nothing at runtime, it's just there to help your tools help you. periodt. πŸ’–
