\r
This function reads a line, stripping any comments.\r
- The function reads a string from the input stream argument and stores it in \r
- the input string. ReadLine reads characters from the current file position \r
- to and including the first newline character, to the end of the stream, or \r
- until the number of characters read is equal to MaxLength - 1, whichever \r
- comes first. The newline character, if read, is replaced with a \0. \r
