Function Documentation

memory_aligned_address()

void* memory_aligned_address	(	void *	addr,
		usize	alignment
	)

Calculate properly aligned memory block address.

Calculate a new address which is a multiple of the alignment provided. At most alignment bytes above provided address.

Parameters

addr	original memory block addr
alignment	number of bytes to be aligned by

Returns

aligned new address

Parameters

size	number of bytes to be allocated

Returns

pointer to beginning of allocated block (zeroed out)

byte	the value to set every byte to
size	number of bytes to be set

Returns

pointer to beginning of the block
