Detailed Description

Low-level memory operations.

Functions to manipulate raw memory blocks.

Function Documentation

ft_bzero()

void ft_bzero	(	void *	s,
		size_t	n
	)

Sets n bytes of memory to zero.

Parameters

s	Pointer to memory area.
n	Number of bytes to set.

Here is the caller graph for this function:

ft_memchr()

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

Locates the first occurrence of a byte in memory.

Note

Returned pointer is borrowed from s. Do not free it directly.

Parameters

s	Memory area to search (borrowed).
c	Byte to search for (converted to unsigned char).
n	Number of bytes to search.

Returns

Pointer to the byte (borrowed), or NULL if not found.

ft_memcmp()

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

Compares two memory areas byte by byte.

Parameters

s1	First memory area.
s2	Second memory area.
n	Number of bytes to compare.

Returns

Difference of first differing bytes, or 0 if equal.

ft_memcpy()

void * ft_memcpy	(	void *	dst,
		const void *	src,
		size_t	n
	)

Copies n bytes from src to dst.

Warning

Memory areas must not overlap. Use ft_memmove for overlapping.

Parameters

dst	Destination memory area (borrowed).
src	Source memory area (borrowed).
n	Number of bytes to copy.

Returns

Pointer to dst.

Here is the caller graph for this function:

ft_memmove()

void * ft_memmove	(	void *	dst,
		const void *	src,
		size_t	len
	)

Copies n bytes from src to dst, handling overlapping memory.

Parameters

dst	Destination memory area.
src	Source memory area.
len	Number of bytes to copy.

Returns

Pointer to dst.

Here is the caller graph for this function:

ft_memset()

void * ft_memset	(	void *	b,
		int	c,
		size_t	len
	)

Fills memory with a constant byte.

Parameters

b	Memory area to fill.
c	Byte value to set (converted to unsigned char).
len	Number of bytes to set.

Returns

Pointer to b.
