Detailed Description

Common utility macros.

Macro Definition Documentation

Round x up to the nearest multiple of align.

#define CU_ARRAY_LEN ( arr ) (sizeof(arr) / sizeof((arr)[0]))

Array element count.

#define CU_BIT ( x ) (1u << (x))

Create a bit mask with bit x set.

Concatenate two tokens after expanding them.

#define CU_DIE ( msg ) cu_panic_handler("Fatal error: %s", msg)

Abort the program with an error message.

#define CU_IF_NOT_NULL ( expr ) if ((expr) != NULL)

Execute the following block if expr is not NULL.

#define CU_IF_NULL ( expr ) if ((expr) == NULL)

Execute the following block if expr is NULL.

#define CU_PLAT_WINDOWS 0

Platform detection macros

#define CU_UNUSED ( expr ) (void)(expr)

Silence unused variable warnings.
