SDL_SIZE_MAX - Man Page
The largest value that a size_t can hold for the target platform.
Header File
Defined in SDL3/SDL_stdinc.h
Synopsis
#include "SDL3/SDL.h" #define SDL_SIZE_MAX SIZE_MAX
Description
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!
Availability
This macro is available since SDL 3.2.0.
