Public Methods
	CNCL (void)

	Defining the destructor virtual provides virtual destructors for all classes derived from CNCL as well as from CNObject.
Static Public Methods
void	initialize ()
	Initialization of the CNCL: Sets the new handler.
ErrorType	get_error ()
	Get error handler setting.
ErrorType	set_error (ErrorType new_error)
	Set error handler setting.
void	set_exit_handler (void(*func)())
	To set the function which should be called when the program is terminated, call the function with your exit handler.
void	default_exit_handler ()
	This function is the default exit handler when no other exit handler is defined using the method CNCL::set_exit_handler.

Error handler functions
void	error (const char *msg1=NIL, const char *msg2=NIL, const char *msg3=NIL, const char *msg4=NIL, const char *msg5=NIL, const char *msg6=NIL)
	The error function is called whenever a general error has been detected.
void	fatal (const char *msg1=NIL, const char *msg2=NIL, const char *msg3=NIL, const char *msg4=NIL, const char *msg5=NIL, const char *msg6=NIL)
	The fatal function is called whenever a fatal error has been detected.
void	warning (const char *msg1=NIL, const char *msg2=NIL, const char *msg3=NIL, const char *msg4=NIL, const char *msg5=NIL, const char *msg6=NIL)
	The error function is called whenever a general error has been detected.
void	info (const char *msg1=NIL, const char *msg2=NIL, const char *msg3=NIL, const char *msg4=NIL, const char *msg5=NIL, const char *msg6=NIL)
	The error function is called whenever a general error has been detected.
void	error (ErrorType err, const char *msg1=NIL, const char *msg2=NIL, const char *msg3=NIL, const char *msg4=NIL, const char *msg5=NIL, const char *msg6=NIL)
	This error function is called by the error and warning functions error, fatal, warning and info with different ErrorTypes in dependence on the severity of the occuring error.

Detailed Description

The top-level class of the CNCL hierarchy.

The class cares about

• error handling
• general settings

The CNCL class contains only static members and functions for the class library's parameters and error handling. All classes in the CNCL hierarchy can directly access the static member functions, other code can call them via CNCL::func().

Member Enumeration Documentation

enum CNCL::ErrorType

Error handler settings: The class CNCL provides common functionality for error handling. This is used by all classes to issue an error message or warning and terminate the program, if desired. The CNCL library also installs a matherr() handler using CNCL::error for displaying an appropiate error message.
