NAME

       SDL_PRINTF_VARARG_FUNC - Macro that annotates a vararg function that operates like printf.

HEADER FILE

       Defined in SDL3/SDL_stdinc.h

SYNOPSIS

       #include "SDL3/SDL.h"

       #define SDL_PRINTF_VARARG_FUNC( fmtargnumber ) __attribute__ (( format( __printf__, fmtargnumber, fmtargnumber+1 )))

DESCRIPTION

       If we were to annotate fprintf :

              int fprintf(FILE *f, const char *fmt, ...) SDL_PRINTF_VARARG_FUNC(2);

       This  notes  that  the  second  parameter  should be a printf-style format string, followed by ...  . 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.

       This can (and should) be used with

       SDL_PRINTF_FORMAT_STRING
        as well, which between them will cover at least Visual Studio, GCC, and Clang.

AVAILABILITY

       This macro is available since SDL 3.2.0.
