| michael@0 | 15 | /* Define PNG_DEBUG at compile time for debugging information. Higher |
| michael@0 | 16 | * numbers for PNG_DEBUG mean more debugging information. This has |
| michael@0 | 17 | * only been added since version 0.95 so it is not implemented throughout |
| michael@0 | 18 | * libpng yet, but more support will be added as needed. |
| michael@0 | 19 | * |
| michael@0 | 20 | * png_debug[1-2]?(level, message ,arg{0-2}) |
| michael@0 | 21 | * Expands to a statement (either a simple expression or a compound |
| michael@0 | 22 | * do..while(0) statement) that outputs a message with parameter |
| michael@0 | 23 | * substitution if PNG_DEBUG is defined to 2 or more. If PNG_DEBUG |
| michael@0 | 24 | * is undefined, 0 or 1 every png_debug expands to a simple expression |
| michael@0 | 25 | * (actually ((void)0)). |
| michael@0 | 26 | * |
| michael@0 | 27 | * level: level of detail of message, starting at 0. A level 'n' |
| michael@0 | 28 | * message is preceded by 'n' 3-space indentations (not implemented |
| michael@0 | 29 | * on Microsoft compilers unless PNG_DEBUG_FILE is also |
| michael@0 | 30 | * defined, to allow debug DLL compilation with no standard IO). |
| michael@0 | 31 | * message: a printf(3) style text string. A trailing '\n' is added |
| michael@0 | 32 | * to the message. |
| michael@0 | 33 | * arg: 0 to 2 arguments for printf(3) style substitution in message. |
