string fgets(int fp, int length);Returns a string of up to length - 1 bytes read from the file pointed to by fp. Reading ends when length - 1 bytes have been read, on a newline, or on EOF (whichever comes first).
If an error occurs, returns false.
The file pointer must be valid, and must point to a file successfully opened by fopen(), popen(), or fsockopen().
