Returns

If successful, returns the next requested object from the stream. Character values are returned as an unsigned char converted to an int. If the stream is at end-of-file or a read error occurs, the routines return Stdlib.EOF. The routines Stdlib.feof(3) and Stdlib.ferror(3) must be used to distinguish between end-of-file and error. If an error occurs, use Stdlib.GetLastError indicates the error. The end-of-file condition is remembered, even on a terminal, and all subsequent attempts to read will return Stdlib.EOF until the condition is cleared with Stdlib.clearerr(3).
