Return a pointer to the start of the array, like:

int* getArray(int numElements) {
   int* theArray = malloc(sizeof(int) * numElements);
   return theArray;
}

...you can use it like:

int* myArray = getArray(3);
myArray[0] = 1;
myArray[1] = 2;
myArray[2] = 3;

//do this when you are done with it
free(myArray);
