Detailed Description

Portable type definitions for C89/C99/C11 compatibility.

Provides fixed width integer types, bool, and NULL for use across all C standards. On C99 and later the standard headers are used directly. On C89 portable fallbacks are provided with compile time size verification.

Macro Definition Documentation

TR_STATIC_ASSERT

#define TR_STATIC_ASSERT	(		condition,
			message
	)		typedef char tr_static_assert_##message[(condition) ? 1 : -1]

Compile time assertion macro.

Triggers a compile error if condition is false. On C11 and later uses _Static_assert. On C89/C99 uses the array size trick.

Parameters

condition	Expression to evaluate at compile time
message	Token used as the error identifier — no spaces allowed

Example usage:

TR_STATIC_ASSERT(sizeof(int) == 4, int_must_be_4_bytes);

Enumeration Type Documentation

bool

enum bool

Boolean type.

On C++ uses the native bool type. On C99 and later includes stdbool.h. On C89 provides a portable enum fallback with values false = 0 and true = 1, matching C99 exactly.

Enumerator
false	Boolean false value - evaluates to 0
true	Boolean true value - evaluates to 1
