EBADF -- A function tried to use a bad file descriptor (it doesn't refer to an open file, for example, or it was used in an attempt to write to a file that was opened read-only).

Note: the "r" used in fopen indicates that the file is open for reading only.
以只读方式打开，放置在文件开头的文件指针。
Open for reading only; place the file pointer at the beginning of the file.
