4 | * Copyright (C) 1991-1998, Thomas G. Lane. | ||
5 | * This file is part of the Independent JPEG Group's software. | ||
6 | * For conditions of distribution and use, see the accompanying README file. | ||
7 | * | ||
8 | * This file contains simple error-reporting and trace-message routines. | ||
9 | * These are suitable for Unix-like systems and others where writing to | ||
10 | * stderr is the right thing to do. Many applications will want to replace | ||
11 | * some or all of these routines. | ||
12 | * | ||
13 | * If you define USE_WINDOWS_MESSAGEBOX in jconfig.h or in the makefile, | ||
14 | * you get a Windows-specific hack to display error messages in a dialog box. | ||
15 | * It ain't much, but it beats dropping error messages into the bit bucket, | ||
16 | * which is what happens to output to stderr under most Windows C compilers. | ||
17 | * | ||
18 | * These routines are used by both the compression and decompression code. | ||
