分配的嵌套结构指针。我希望在二进制文件中打印数组，然后将其加载到此结构中再次破坏现有记录。这是我的结构数组：
malloc我正在尝试将其打印在二进制文件中，如：
struct viaje {
char *identificador;
char *ciudadDestino;
char *hotel;
int numeroNoches;
char *tipoTransporte;
float precioAlojamiento;
float precioDesplazamiento;
};
struct cliente {
char *dni;
char *nombre;
char *apellidos;
char *direccion;
int totalViajes;
struct viaje *viajes;
} *clientes;
其中：
for (i = 0; i < MAX_TAM_CLIENTES; i++) {
fwrite(&clientes[i], sizeof(struct cliente)-(sizeof(struct viaje)*MAX_TAM_VIAJES_CLIENTE), 1, fp_guardarCargarEstado);
for (j = 0; j < clientes[i].totalViajes; j++) {
fwrite(&clientes[i].viajes[j], sizeof(struct viaje), 1, fp_guardarCargarEstado);
}
}
是一个定义。是数组MAX_TAM_CLIENTES的最大大小，
clientes是一个定义。是一个客户端中数组MAX_TAM_VIAJES_CLIENTE的最大大小
另外，我尝试加载这样的二进制数据，如：
viajes其中：
for (i = 0; i < MAX_TAM_CLIENTES; i++) {
clientes = (struct cliente *)realloc(clientes, (totalClientes+1)*sizeof(struct cliente));
clientes[totalClientes].dni = (char *)malloc((MAX_TAM_DNI+1)*sizeof(char));
clientes[totalClientes].nombre = (char *)malloc((MAX_TAM_NOMBRE+1)*sizeof(char));
clientes[totalClientes].apellidos = (char *)malloc((MAX_TAM_APELLIDOS+1)*sizeof(char));
clientes[totalClientes].direccion = (char *)malloc((MAX_TAM_DIRECCION+1)*sizeof(char));
fread(&clientes[i], sizeof(struct cliente)-(sizeof(struct viaje)*MAX_TAM_VIAJES_CLIENTE), 1, fp_guardarCargarEstado);
for (j = 0; j < clientes[i].totalViajes; j++) {
clientes[i].viajes = (struct viaje *)realloc(clientes[i].viajes, (j+1)*sizeof(struct viaje));
clientes[i].viajes[j].identificador = (char *)malloc((MAX_TAM_IDENTIFICADOR+1)*sizeof(char));
clientes[i].viajes[j].ciudadDestino = (char *)malloc((MAX_TAM_CIUDAD_DESTINO+1)*sizeof(char));
clientes[i].viajes[j].hotel = (char *)malloc((MAX_TAM_HOTEL+1)*sizeof(char));
clientes[i].viajes[j].tipoTransporte = (char *)malloc((MAX_TAM_TIPO_TRANSPORTE+1)*sizeof(char));
fread(&clientes[i].viajes[j], sizeof(struct viaje), 1, fp_guardarCargarEstado);
}
}
是定义。它们是每个字段的最大大小。
但我不知道MAX_TAM_*是否可以保存好数据，因为当我尝试加载它时，程序崩溃并且没有加载数据。
我不知道那里怎么可能出错。有什么想法吗？
谢谢。
答案 0 :(得分：1)
您无法使用fwrite保存这些结构的全部内容，并使用fread将其读回，因为它们包含指向字符串的指针，而不是实际字符。
有两种方法可以实现目标：
,分隔。char的数组，而不是指向已分配存储的指针。 If you open the files as binary, you should be able to write the structures and read them back with fread`。请注意，后一种方法的灵活性远低于文本方法：
int的表示形式可能不同。struct viaje *viajes;也必须替换为没有任何指针的实际结构。
