I have a "list" struct.
typedef struct list
{
int count; // how many elements are in the list
void *start; // our pointer to the start of the array
unsigned char size; // how many bytes each element will hold
}
list;
And I want to get a void pointer to a specific element in the struct. I’m not sure of the syntax though, it keeps giving me segmentation faults.
static void* dev_list_get(list *list, int index)
{
return (void *)((char *) list->start) + (index * list->size);
}
If we cast the void pointer to a char pointer and add 1 to it then that increases the pointer to the next memory slot in line so we need to increase it by the # of bytes right?
