1.18 +/* Define PNG_DEBUG at compile time for debugging information. Higher
1.19 + * numbers for PNG_DEBUG mean more debugging information. This has
1.20 + * only been added since version 0.95 so it is not implemented throughout
1.21 + * libpng yet, but more support will be added as needed.
1.22 + *
1.23 + * png_debug[1-2]?(level, message ,arg{0-2})
1.24 + * Expands to a statement (either a simple expression or a compound
1.25 + * do..while(0) statement) that outputs a message with parameter
1.26 + * substitution if PNG_DEBUG is defined to 2 or more. If PNG_DEBUG
1.27 + * is undefined, 0 or 1 every png_debug expands to a simple expression
1.28 + * (actually ((void)0)).
1.29 + *
1.30 + * level: level of detail of message, starting at 0. A level 'n'
1.31 + * message is preceded by 'n' 3-space indentations (not implemented
1.32 + * on Microsoft compilers unless PNG_DEBUG_FILE is also
1.33 + * defined, to allow debug DLL compilation with no standard IO).
1.34 + * message: a printf(3) style text string. A trailing '\n' is added
1.35 + * to the message.
1.36 + * arg: 0 to 2 arguments for printf(3) style substitution in message.
