(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_PRINTF_FORMAT_STRING

Macro that annotates function params as printf-style format strings.

Header File

Defined in <SDL3/SDL_stdinc.h>

Syntax

#define SDL_PRINTF_FORMAT_STRING _Printf_format_string_

Remarks

If we were to annotate fprintf:

int fprintf(FILE *f, SDL_PRINTF_FORMAT_STRING const char *fmt, ...);

This notes that fmt should be a printf-style format string. The compiler or other analysis tools can warn when this doesn't appear to be the case.

On compilers without this annotation mechanism, this is defined to nothing.

Version

This macro is available since SDL 3.1.3.
