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

SDL_NULL_WHILE_LOOP_CONDITION

A macro for wrapping code in do {} while (0); without compiler warnings.

Header File

Defined in <SDL3/SDL_assert.h>

Syntax

#define SDL_NULL_WHILE_LOOP_CONDITION (0)

Remarks

Visual Studio with really aggressive warnings enabled needs this to avoid compiler complaints.

the do {} while (0); trick is useful for wrapping code in a macro that may or may not be a single statement, to avoid various C language accidents.

To use:

do { SomethingOnce(); } while (SDL_NULL_WHILE_LOOP_CONDITION (0));

Version

This macro is available since SDL 3.1.3.
