How to resize array of structs?

I have an array of structs that I have defined in a header file:

struct table { 
    otherStruct *list[16];
}

Now I want to be able to resize this array, change the size of the array, or dynamically allocate an array that can replace (or join) the original list in "table" once a condition is met. How can I accomplish this task?

Change the array to a otherStruct ** and malloc a group of (otherStruct *) to the new size of your array. Be sure to free it as well as this will be a new alloc on top of your old ones.

Make list an otherStruct **:

struct table { 
    otherStruct **list;
}

Now you can malloc it to be as big as you want and realloc at will.
