/* 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.
