Function Documentation

bitmap_clear()

void bitmap_clear	(	bitmap_t *	b,
		uint64_t	n )

Clears a bit (sets it to false).

Parameters

b	a bitmap
n	the bit to clear

bitmap_get()

bool bitmap_get	(	const bitmap_t *	b,
		uint64_t	n )

Returns true when the bit is set, false otherwise.

Parameters

b	a bitmap
n	the bit to check

Returns

true when the bit to check is set, false otherwise

bitmap_set()

void bitmap_set	(	bitmap_t *	b,
		uint64_t	n )

Sets a bit (sets it to true).

Parameters

b	a bitmap
n	the bit to set
