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_countThe number of elements
element_sizeThe size of each element
typeThe type of the usage
Returns
void * A pointer to the allocated memory

Returns
void
Author
Nicolas TORO

◆ my_malloc()

void * my_malloc ( size_t size,
int type )

Allocates memory for an array of bytes (size)

Note

◆ my_memcmp()

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

Compares the first (size) bytes of the two memory areas (pointer1 and pointer2)

Parameters
