2D array pointer?

hey...i need to create an array of locations on the hard drive. at least i think thats how i want to do it as i've tried learning linked lists before and they just dont click. idky, but i dont get it. lol but basically i have a program that lets you search non-executable files for a specified string / strings. after the user selects the root dir, i create a dir listing of all of the files of a certain type in that dir and then open the files and search for the string. what i need to do is have a way to keep track of the dir list so i thought, hey a 2D array pointer. when i need to store another location, i can just increase the size of the array and store the new dir where the file is stored so that when the program is closed i can remove the files. so really, my question is how do i make this? i know how to do a 1D array pointer, but not 2D. thanks :]

well its very similar - allocate an array of pointers to your double
pointer, use a loop to step through that, and allocate arrays
for each pointer.

You'll need realloc(), and a variable to hold the size of the array.

Search the board for examples.

for some reason this just isn't clicking.
an array of pointers? like *ptr[10]; ?
and by the double pointer, you mean **pointer , yes?
would you mind a quick example?

thanks guys

Here's what i was talking about - read filker0's post, explains
both allocation and deallocation, and also an alternative approach
