C - Creating Sub Function To realloc Array Size

I'm having an issue with pointers. I've read through 30+ posts on this subject and none match my setup. Here's what I'm trying to do:

void doSomething(myStruct **myList)
{
    resizeMyList(myList,5);

    myList[0] = '42';
    myList[1] = '43'; // ERRORS OUT OF MEMORY
}

void resizeMyList(myStruct **theArray,int size)
{
    myStruct *new_ptr = realloc(*theArray,(size * sizeof myStruct));

    if(new_ptr)
         *theArray = new_ptr;
    else
         printf("died");
}

After my resize function executes myList fails to get the new pointer. What am I doing wrong?

Solution

  • You do

    myList[0] = ...

    but myList is a double pointer so it should be

    (*myList)[0] = ...

    Also, you try to assign multi-character literals to a structure.
