Hi,how do we use perror? Does it only prints out the error message?
If so , why don't we use printf instead?

Thanks.

Do you know why some fopen call failed? Using perror might give a better error message, like "no such file or directory", "permission denied", or "too many open files".

But sure, you could also do something like this.

puts(strerror(errno));
