Detailed Description

Standard C memory functions (defined in cstring.h, stdlib.h)

Function Documentation

void* calloc	(	size_t	num_elems,
		size_t	elem_size
	)

Documented at http://www.cplusplus.com/reference/cstdlib/calloc/.

void free

(

void *

mem_address

)

Documented at http://www.cplusplus.com/reference/cstdlib/free/.

void* malloc

(

size_t

num_bytes

)

Documented at http://www.cplusplus.com/reference/cstdlib/malloc/.

void* memchr	(	const void *	s,
		int	c,
		size_t	n
	)

Documented at http://www.cplusplus.com/reference/cstring/memchr/.

int memcmp	(	const void *	s1,
		const void *	s2,
		size_t	n
	)

Documented at http://www.cplusplus.com/reference/cstring/memcmp/.

void* memcpy	(	void *	dest,
		const void *	src,
		size_t	n
	)

Documented at http://www.cplusplus.com/reference/cstring/memcpy/.

Note

The operation of memcpy is not guaranteed on overlap, use memmove instead

void* memmove	(	void *	dest,
		const void *	src,
		size_t	n
	)

Documented at http://www.cplusplus.com/reference/cstring/memmove/.

void* memset	(	void *	buffer,
		int	c,
		size_t	n
	)

Documented at http://www.cplusplus.com/reference/cstring/memset/.

void* realloc	(	void *	mem_address,
		size_t	size
	)

Documented at http://www.cplusplus.com/reference/cstdlib/realloc/.

Note

::{realloc}(NULL, size) === ::{malloc}(size)
