Function Documentation

ft_bzero()

void ft_bzero	(	void *	s,
		size_t	n )

Set at 0, the n first bytes at the pointer adress.

Parameters

s	pointer to the memory to set
n	number of bytes to set at 0

ft_calloc()

void * ft_calloc	(	size_t	element_count,
		size_t	element_size )

Allocates a new memory zone, and set all bits to zero.

Parameters

element_count	number of elements
element_size	size of each element

Returns

void* pointer to the new memory zone

Here is the call graph for this function:

ft_memchr()

const void * ft_memchr	(	const void *	memory_block,
		int	searched_char,
		size_t	size )

Research the first occurence of a value typed int, but interpreted as a char in a memory block.

Parameters

memory_block	memory block to search in
searched_char	value to search
size	size of the memory block

Returns

void* pointer to the first occurence of the value or NULL if not found

ft_memcmp()

int ft_memcmp	(	const void *	src,
		const void *	set,
		size_t	size )

Compares the first size bytes of the memory areas src and set.

Parameters

src	source memory block
set	set memory block
size	size of the memory block

Returns

int difference between the first different byte

ft_memcpy()

void * ft_memcpy	(	void *	destination,
		const void *	source,
		size_t	size )

Set a memory zone with a value, count times.

Parameters

destination	memory zone to paste
source	memory zone to copy
size	number of times to set the value

Returns

void* pointer to the memory zone

ft_memmove()

void * ft_memmove	(	void *	destination,
		const void *	source,
		size_t	size )

Moves the memory blocks avoiding overlapping, until size blocks.

Parameters

destination	destination memory block
source	source memory block
size	size of the memory block

Returns

void* pointer to the destination memory block

ft_memset()

void * ft_memset	(	void *	pointer,
		int	value,
		size_t	count )

Set a memory zone with a value, count times.

Parameters

pointer	memory zone to set
value	value to set
count	number of times to set the value

Returns

void* pointer to the memory zone
