    Question Saving linked lists to a binary file

    I'm trying to do the code to store a linked list to a binary file.

    My strutures are:
    Code:
    typedef struct
    {
    	char nome[25];
    	Coordenadas localizacao;
    	char morada[100];
    	char email[25];
    	char tipoComida[25];
    	Data feriasInicio;
    	Data feriasFim;
    	int diaDescanso;
    	char periodoFerias[25];
    	int numeroTelefone;
    } Restaurante;
    
    typedef struct No
    {
    	Restaurante* restaurante;
    	struct No* proximo;
    	
    } No;
    I'm not sure if I can simply store the No structs since they have only pointers. I already did a first try and the code does not work properly and doesn't always have the same behaviour so I'm wondering if that's the problem.

    Any ideas?

    Thanks in advance

    You can't directly write the struct No's to memory, since there's no data there (and even if there was, reading pointers in from files never works, since who knows where the data will be stored this time?) You need to walk the list and write the Restaurantes to a file.
