/*
 * The ft_bzero function fills the first 'n' bytes of the memory
 * area pointed to by 'pointer' with zeros.
 *
 * It takes two arguments: a pointer 'pointer' to the memory area
 * to be filled, and a size_t 'count' which is the size of the
 * memory area to be filled.
 *
 * It does not return anything. This function is generally used
 * to initialize a memory area to zero.
