NAME
SDL_SINT64_C - Append the 64 bit integer suffix to a signed integer literal.
SYNOPSIS
#include <SDL3/SDL_stdinc.h>
#define SDL_SINT64_C(c) c ## LL /* or whatever the current compiler uses. */
DESCRIPTION
This helps compilers that might believe a integer literal larger than 0xFFFFFFFF is overflowing a 32-bit
value. Use SDL_SINT64_C(0xFFFFFFFF1) instead of 0xFFFFFFFF1 by itself.
AVAILABILITY
This macro is available since SDL 3.2.0.
