SDL_UINT64_C

Append the 64 bit integer suffix to an unsigned integer literal.

Header File

Defined in <SDL3/SDL_stdinc.h>

Syntax

#define SDL_UINT64_C(c)  c ## ULL /* or whatever the current compiler uses. */

Remarks

This helps compilers that might believe a integer literal larger than 0xFFFFFFFF is overflowing a 32-bit value. Use SDL_UINT64_C(0xFFFFFFFF1) instead of 0xFFFFFFFF1 by itself.

Version

This macro is available since SDL 3.2.0.
