(sorry for my first uncomplete email, please abandon the first mail) Hi All, Sometimes i see codes are written like this: (void) printf(fmt); - or - (void) close(fd); What these means? i think it is not necessary to put that 'void' on a statement, or it just like when we cast a data type like: double d = 93.43; int i = (int) d; but why those function need to be casted in a 'void' ?
