Functions
void	AbstractMethod (const char *method)
	This function can be used in abstract base classes in case one does not want to make the class a "real" (in C++ sense) ABC.

void	Break (const char location, const char fmt,...)
	Use this function in case an error occurred.

void	Error (const char location, const char fmt,...)
	Use this function in case an error occurred.

void	ErrorHandler (Int_t level, const char location, const char fmt, std::va_list ap)
	General error handler function. It calls the user set error handler.

void	Fatal (const char location, const char fmt,...)
	Use this function in case of a fatal error. It will abort the program.

ErrorHandlerFunc_t	GetErrorHandler ()
	Returns the current error handler function.

ErrorSystemMsgHandlerFunc_t	ROOT::Internal::GetErrorSystemMsgHandler ()

static ROOT::Internal::ErrorSystemMsgHandlerFunc_t &	GetErrorSystemMsgHandlerRef ()

void	Info (const char location, const char fmt,...)
	Use this function for informational messages.

void	MayNotUse (const char *method)
	This function can be used in classes that should override a certain function, but in the inherited class the function makes no sense.

void	ROOT::Internal::MinimalErrorHandler (Int_t level, Bool_t abort_bool, const char location, const char msg)
	A very simple error handler that is usually replaced by the TROOT default error handler.

void	Obsolete (const char function, const char asOfVers, const char *removedFromVers)
	Use this function to declare a function obsolete.

ErrorHandlerFunc_t	SetErrorHandler (ErrorHandlerFunc_t newhandler)
	Set an errorhandler function. Returns the old handler.

ErrorSystemMsgHandlerFunc_t	ROOT::Internal::SetErrorSystemMsgHandler (ErrorSystemMsgHandlerFunc_t h)
	Returns the previous system error message handler.

void	SysError (const char location, const char fmt,...)
	Use this function in case a system (OS or GUI) related error occurred.

void	Warning (const char location, const char fmt,...)
	Use this function in warning situations.

Function Documentation

◆ AbstractMethod()

void AbstractMethod ( const char * method )

This function can be used in abstract base classes in case one does not want to make the class a "real" (in C++ sense) ABC.

If this function is called it will warn the user that the function should have been overridden.

Definition at line 171 of file TError.cxx.

◆ Break()

void Break	(	const char *	location,
		const char *	fmt,
			...
	)

Use this function in case an error occurred.

Definition at line 219 of file TError.cxx.

◆ Error()

void Error	(	const char *	location,
		const char *	fmt,
			...
	)

Use this function in case an error occurred.

Definition at line 197 of file TError.cxx.

◆ ErrorHandler()

void ErrorHandler	(	Int_t	level,
		const char *	location,
		const char *	fmt,
		std::va_list	ap
	)

General error handler function. It calls the user set error handler.

Definition at line 121 of file TError.cxx.

◆ Fatal()

void Fatal	(	const char *	location,
		const char *	fmt,
			...
	)

Use this function in case of a fatal error. It will abort the program.

Warning

Fatal() will not abort the program if gErrorIgnoreLevel > kFatal

but for all reasonable settings it will abort.

Definition at line 256 of file TError.cxx.

◆ GetErrorHandler()

ErrorHandlerFunc_t GetErrorHandler ( )

Returns the current error handler function.

Definition at line 112 of file TError.cxx.

◆ GetErrorSystemMsgHandlerRef()

static ROOT::Internal::ErrorSystemMsgHandlerFunc_t & GetErrorSystemMsgHandlerRef ( )

static

Definition at line 53 of file TError.cxx.

◆ Info()

void Info	(	const char *	location,
		const char *	fmt,
			...
	)

Use this function for informational messages.

Definition at line 230 of file TError.cxx.

◆ MayNotUse()

void MayNotUse ( const char * method )

This function can be used in classes that should override a certain function, but in the inherited class the function makes no sense.

Definition at line 180 of file TError.cxx.

◆ Obsolete()

void Obsolete	(	const char *	function,
		const char *	asOfVers,
		const char *	removedFromVers
	)

Use this function to declare a function obsolete.

Specify as of which version the method is obsolete and as from which version it will be removed.

Definition at line 189 of file TError.cxx.

◆ SetErrorHandler()

ErrorHandlerFunc_t SetErrorHandler ( ErrorHandlerFunc_t newhandler )

Set an errorhandler function. Returns the old handler.

Definition at line 102 of file TError.cxx.

◆ SysError()

void SysError	(	const char *	location,
		const char *	fmt,
			...
	)

Use this function in case a system (OS or GUI) related error occurred.

Definition at line 208 of file TError.cxx.

◆ Warning()

void Warning	(	const char *	location,
		const char *	fmt,
			...
	)

Use this function in warning situations.

Definition at line 241 of file TError.cxx.

◆ gErrorMutex

TVirtualMutex* gErrorMutex = nullptr

Error handling routines.

This file defines a number of global error handling routines: Warning(), Error(), SysError() and Fatal(). They all take a location string (where the error happened) and a printf style format string plus vararg's. In the end these functions call an errorhandler function. Initially the MinimalErrorHandler, which is supposed to be replaced by the proper DefaultErrorHandler()
