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

       This macro is available since SDL 3.2.0.

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!
