Thread: Struct with a ptr to a dynamically allocated array of other structures :(

I can't really make that description any simpler. I need help accessing a certain element of a dynamically allocated array of structures, and my only access to the array is a pointer contained in another structure. Here are the structures:

Code:

struct Country
{
	int	continent;
	char * name;
	char * cap;
	char * lang;
};

struct Database
{
	struct Country * list;
	int ncountries;
	char * filename;
};

And here is my function that needs to find the first "empty" element of the array:

Code:

//insert_database: insert ctry into the right element of db list
void insert_database( struct Database * db, struct Country * ctry )
{
	int insertAt;

    if( db != NULL && ctry != NULL )
    {
		for( int i = 0, insertAt = 0; i < db->ncountries; i++ )
		{
			if( db[i].list == NULL )
			{
				insertAt = i;
				printf( "Insert here: %d\n", insertAt );

				//copy_country( db, ctry, i );

				break;
			}
		}
    }
}

Help?! I've been browsing the internet for help on this, and I can't find anything. This is confusing the crap out of me.
