Help with some C

[Sirrius]

I have some C code here, my teachers, that I'm trying to rifle through and figure out. I am confused on on line of it: The second line down is

*b = (int*) malloc ( n * sizeof(int));

does this mean a integer pointer that point to a memory location that is 4 times the size of an integer? Which would be then 16 bytes. So a int pointer that points to 16 bytes of vacant memory. Am I right, close or way off. Please help. the code below is what it is out of. Thanks for your help.

#include "stdio.h"

void ByteSwap4_c(int n, int *a);
void ByteSwap4_asm(int n, int *a);

void ByteSwap4(int n, int *a)
{
int i;
int *b = (int*) malloc ( n * sizeof(int));
for (i=0; i

void ByteSwap4_c(int n, int *a)
{
int i;
for (i=0; i

The malloc() call allocates space for a table of n integers.
