一种这样做的方法是：

struct bus_trip {
 /* your variables here */
};

int reserve_trip(struct bus_trip *parg){
 /* ... */
 /* use your record */
 scanf("%s", parg->name);
 return 0;
}

int main(){

 struct bus_trip trip = {
  .idnumber = /* your default, or comuted id */
  /* rest of the defualts */
 };

 reserve_trip(&trip); /* get an address of a variable */
 /* rest of your code */
}
