fwrite() not working to write integer in binary file

Question

Can someone tell my why won\'t this function work? I just can\'t get it...

void writeRegister(FILE *arq, Book *L){ //writes in actual file position
  char          


        

Answer 1

You must pass the address of L->YEAR to fwrite

fwrite(L->YEAR, sizeof(int), 1, arq);

fwrite(&(L->YEAR), sizeof(int), 1, arq);
