/*
 * This file contains a few useful functions from the original
 * z88dk stdio library
 *
 * All these operate on a file handle fd (as supplied by open)
 * (or by the fopen in this file
 *
 * If porting, don't bother with these - more hassle than they're
 * worth!
 *
 * Use these routines by #define FDSTDIO and linking with -lz88
 *
 * Most of these return non-ANSI return values or are just very
 * slightly messed up!
 *
 * These routines are not supported!!!
