/* pngdebug.h - Debugging macros for libpng, also used in pngtest.c * * Copyright (c) 1998-2013 Glenn Randers-Pehrson * (Version 0.96 Copyright (c) 1996, 1997 Andreas Dilger) * (Version 0.88 Copyright (c) 1995, 1996 Guy Eric Schalnat, Group 42, Inc.) * * Last changed in libpng 1.6.8 [December 19, 2013] * * This code is released under the libpng license. * For conditions of distribution and use, see the disclaimer * and license in png.h */ /* Define PNG_DEBUG at compile time for debugging information. Higher * numbers for PNG_DEBUG mean more debugging information. This has * only been added since version 0.95 so it is not implemented throughout * libpng yet, but more support will be added as needed. * * png_debug[1-2]?(level, message ,arg{0-2}) * Expands to a statement (either a simple expression or a compound * do..while(0) statement) that outputs a message with parameter * substitution if PNG_DEBUG is defined to 2 or more. If PNG_DEBUG * is undefined, 0 or 1 every png_debug expands to a simple expression * (actually ((void)0)). * * level: level of detail of message, starting at 0. A level 'n' * message is preceded by 'n' 3-space indentations (not implemented * on Microsoft compilers unless PNG_DEBUG_FILE is also * defined, to allow debug DLL compilation with no standard IO). * message: a printf(3) style text string. A trailing '\n' is added * to the message. * arg: 0 to 2 arguments for printf(3) style substitution in message. */ #ifndef PNGDEBUG_H #define PNGDEBUG_H /* These settings control the formatting of messages in png.c and pngerror.c */ /* Moved to pngdebug.h at 1.5.0 */ # ifndef PNG_LITERAL_SHARP # define PNG_LITERAL_SHARP 0x23 # endif # ifndef PNG_LITERAL_LEFT_SQUARE_BRACKET # define PNG_LITERAL_LEFT_SQUARE_BRACKET 0x5b # endif # ifndef PNG_LITERAL_RIGHT_SQUARE_BRACKET # define PNG_LITERAL_RIGHT_SQUARE_BRACKET 0x5d # endif # ifndef PNG_STRING_NEWLINE # define PNG_STRING_NEWLINE "\n" # endif #ifdef PNG_DEBUG # if (PNG_DEBUG > 0) # if !defined(PNG_DEBUG_FILE) && defined(_MSC_VER) # include <crtdbg.h> # if (PNG_DEBUG > 1) # ifndef _DEBUG # define _DEBUG # endif # ifndef png_debug # define png_debug(l,m) _RPT0(_CRT_WARN,m PNG_STRING_NEWLINE) # endif # ifndef png_debug1 # define png_debug1(l,m,p1) _RPT1(_CRT_WARN,m PNG_STRING_NEWLINE,p1) # endif # ifndef png_debug2 # define png_debug2(l,m,p1,p2) \ _RPT2(_CRT_WARN,m PNG_STRING_NEWLINE,p1,p2) # endif # endif # else /* PNG_DEBUG_FILE || !_MSC_VER */ # ifndef PNG_STDIO_SUPPORTED # include <stdio.h> /* not included yet */ # endif # ifndef PNG_DEBUG_FILE # define PNG_DEBUG_FILE stderr # endif /* PNG_DEBUG_FILE */ # if (PNG_DEBUG > 1) # ifdef __STDC__ # ifndef png_debug # define png_debug(l,m) \ do { \ int num_tabs=l; \ fprintf(PNG_DEBUG_FILE,"%s" m PNG_STRING_NEWLINE,(num_tabs==1 ?
