	Retrieves the error string associated with the last system error.

Functions

	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 in case a system (OS or GUI) related error occurred.
void	Warning (const char location, const char msgfmt,...)
	Use this function in warning situations.

Variables

Macro Definition Documentation

◆ R__ASSERT

#define R__ASSERT ( e )

Value:

do {                                                           \
   if (R__unlikely(!(e)))                                      \
      ::Fatal("", kAssertMsg, _QUOTE_(e), __LINE__, __FILE__); \
} while (false)

Checks condition e and reports a fatal error if it's false.

Warning

this check is NOT stripped in release mode, so it should not be used for hot paths. For those cases, prefer a regular assert();
depending on gErrorIgnoreLevel, this might not terminate the program,

See also: Fatal.

Definition at line 125 of file TError.h.

◆ R__CHECK

#define R__CHECK ( e )

Value:

do {                                                            \
   if (R__unlikely(!(e)))                                       \
      ::Warning("", kCheckMsg, _QUOTE_(e), __LINE__, __FILE__); \
} while (false)

Checks condition e and reports a warning message if it's false.

Warning: this check is NOT stripped in release mode, so it should not be used for hot paths.

Definition at line 134 of file TError.h.

◆ ErrorHandlerFunc_t

typedef void(* ErrorHandlerFunc_t) (int level, Bool_t abort, const char *location, const char *msg)

Definition at line 71 of file TError.h.

Function Documentation

◆ AbstractMethod()

void AbstractMethod ( const char * method )

extern

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 182 of file TError.cxx.

◆ Break()

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

extern

Use this function in case an error occurred.

Definition at line 230 of file TError.cxx.

◆ DefaultErrorHandler()

void DefaultErrorHandler	(	Int_t	level,
		Bool_t	abort_bool,
		const char *	location,
		const char *	msg )

extern

The default error handler function.

It prints the message on stderr and if abort is set it aborts the application. Replaces the minimal error handler of TError.h as part of the gROOT construction. TError's minimal handler is put back in place during the gROOT destruction.

Note: abort() is only called if abort_bool is true and level >= gErrorIgnoreLevel

Definition at line 102 of file TErrorDefaultHandler.cxx.

◆ Error()

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

extern

Use this function in case an error occurred.

Definition at line 208 of file TError.cxx.

◆ ErrorHandler()

void ErrorHandler	(	int	level,
		const char *	location,
		const char *	fmt,
		std::va_list	va )

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

Definition at line 111 of file TError.cxx.

◆ Fatal()

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

extern

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 267 of file TError.cxx.

◆ GetErrorHandler()

ErrorHandlerFunc_t GetErrorHandler ( )

extern

Returns the current error handler function.

Definition at line 102 of file TError.cxx.

			... )

extern

Use this function for informational messages.

Definition at line 241 of file TError.cxx.

◆ MayNotUse()

void MayNotUse ( const char * method )

extern

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 191 of file TError.cxx.

◆ Obsolete()

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

extern

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 200 of file TError.cxx.

◆ SetErrorHandler()

Definition at line 219 of file TError.cxx.

◆ Warning()

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

extern

Use this function in warning situations.

Definition at line 252 of file TError.cxx.
