Define Documentation

#define XklDebug (  level, format, args...    )     _XklDebug( __FILE__, __func__, level, format, ## args )

Output (optionally) some debug info Parameters: level  is a level of the message format  is a format (like in printf) See also: _XklDebug

Typedef Documentation

typedef void( * XklLogAppender)( const char file[], const char function[], int level, const char format[], va_list args )

Custom log output method for _XklDebug. This appender is NOT called if the level of the message is greater than currently set debug level. Parameters: file  is the name of the source file. Preprocessor symbol__FILE__ should be used here function  is a name of the function Preprocessor symbol__func__ should be used here level  is a level of the message format  is a format (like in printf) args  is the list of parameters See also: _XklDebug , XklSetDebugLevel

Function Documentation

void _XklDebug (  const char    file[], const char    function[], int    level, const char    format[], ...    )

Output (optionally) some debug info Parameters: file  is the name of the source file. Preprocessor symbol__FILE__ should be used here function  is a name of the function Preprocessor symbol__func__ should be used here level  is a level of the message format  is a format (like in printf) See also: XklDebug

void XklDefaultLogAppender (  const char    file[], const char    function[], int    level, const char    format[], va_list    args )

Default log output method. Sends everything to stdout. Parameters: file  is the name of the source file. Preprocessor symbol__FILE__ should be used here function  is a name of the function Preprocessor symbol__func__ should be used here level  is a level of the message format  is a format (like in printf) args  is the list of parameters

const char* XklGetLastError (  void    )

Returns: the text message (statically allocated) of the last error

void XklSetDebugLevel (  int    level )

Sets maximum debug level. Message of the level more than the one set here - will be ignored Parameters: level  is a new debug level

void XklSetLogAppender (  XklLogAppender    fun )

Installs the custom log appender.function Parameters: fun  is the new log appender
