NAME

       SDL_COMPILE_TIME_ASSERT - A compile-time assertion.

SYNOPSIS

       #include <SDL3/SDL_stdinc.h>

       #define SDL_COMPILE_TIME_ASSERT(name, x) FailToCompileIf_x_IsFalse(x)

DESCRIPTION

       This can check constant values _known to the compiler at build time_ for correctness, and end the compile
       with the error if they fail.

       Often times these are used to verify basic truths, like the size of a datatype is what is expected:

              SDL_COMPILE_TIME_ASSERT(uint32_size, sizeof(Uint32) == 4);

       The  name  parameter  must be a valid C symbol, and must be unique across all compile-time asserts in the
       same compilation unit (one run of the compiler), or the build might fail  with  cryptic  errors  on  some
       targets.  This  is  used  with a C language trick that works on older compilers that don't support better
       assertion techniques.

       If you need an assertion that operates at runtime, on variable data, you should try SDL_assert instead.

MACRO PARAMETERS

       name   a unique identifier for this assertion.

       x      the value to test. Must be a boolean value.

THREAD SAFETY

       This macro doesn't generate any code to run.

AVAILABILITY

       This macro is available since SDL 3.2.0.
