Function Documentation

DebugPrint()

static void DebugPrint ( const char *  fmt,   ...  )

static

Print debugging message to stderr and, on Windows, to the system debugger.

Definition at line 57 of file TErrorDefaultHandler.cxx.

DefaultErrorHandler()

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

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.

GetErrorMutex()

static std::mutex * GetErrorMutex ( )

static

Serializes error output, destructed by the gROOT destructor via ReleaseDefaultErrorHandler()

Definition at line 38 of file TErrorDefaultHandler.cxx.
