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

SDL_SIZE_MAX

The largest value that a size_t can hold for the target platform.

Header File

Defined in <SDL3/SDL_stdinc.h>

Syntax

#define SDL_SIZE_MAX SIZE_MAX

Remarks

size_t is generally the same size as a pointer in modern times, but this can get weird on very old and very esoteric machines. For example, on a 16-bit Intel 286, you might have a 32-bit "far" pointer (16-bit segment plus 16-bit offset), but size_t is 16 bits, because it can only deal with the offset into an individual segment.

In modern times, it's generally expected to cover an entire linear address space. But be careful!

Version

This macro is available since SDL 3.1.3.
