my_calloc()

void * my_calloc	(	size_t	element_count,
		size_t	element_size,
		int	type )

Allocates memory for an array of elements (element_count) of bytes (element_size) each and initializes the memory to zero.

Note

type = 0: Free allocated memory with my_calloc

type = 1: Allocate memory

Parameters

element_count	The number of elements
element_size	The size of each element
type	The type of the usage

Returns

void * A pointer to the allocated memory

my_malloc()

void * my_malloc	(	size_t	size,
		int	type )

Allocates memory for an array of bytes (size)

Note

type = 0: Free allocated memory with my_malloc

type = 1: Allocate memory

Parameters

size	The size of the memory to allocate
type	The type of the usage

Returns

void * A pointer to the allocated memory

my_malloc_strdup_word_array()

char ** my_malloc_strdup_word_array

(

char **

array

)

Duplicates a word array (array) with my_malloc.

Note

The duplicated word array must be free only with my_free

Parameters

array

The word array to duplicate

Returns

char ** A pointer to the duplicated word array

Author

my_malloc_strndup()

char * my_malloc_strndup	(	char const *	src,
		int	n )

Duplicates a string with a defined size with my_malloc.

Note

The duplicated string must be free only with my_free

Parameters

src	The string to duplicate
n	The size of the string

Returns

my_memchr()

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

Copies bytes (size) from memory area (source) to memory area (destination)

Parameters

destination	The destination memory area
source	The source memory area
size	The number of bytes to copy

Returns

void * A pointer to the destination memory area

Author

my_memcmp()

int my_memcmp	(	const void *	pointer1,
		const void *	pointer2,
		size_t	size )
