How to dynamically allocate array of pointers?

Question

I am currently implementing a program for file copy from one directory to another and in that program i need to allocate memory dynamically for the pointers.So is it possible to allocate memory dynamically for the array of pointers? if yes please guide me.
Thanks...

Answer 1

This dynamically allocates an array of n pointers to char:

char **p;
int n = 42;
p = malloc(n * sizeof *p);

You can then access the array like any array:

int i;
// Initialize all pointers to NULL
for (i = 0; i < n; i++)
{
 p[i] = NULL;
}
