is output. Before the stopped annotation, a variety of annotations describe how the program stopped.

^Z^Zexited exit-status	The program exited, and exit-statusis the exit
	status (zero for successful exit, otherwise nonzero).
^Z^Zsignalled	The program exited with a signal. After the
	^Z^Zsignalled, the annotation continues:
	intro-text
	^Z^Zsignal-name
	name
	^Z^Zsignal-name-end
	middle-text
	^Z^Zsignal-string
	string
	^Z^Zsignal-string-end
	end-text
	where name is the name of the signal, such as
	SIGILL or SIGSEGV, and string is the explanation
	of the signal, such as Illegal Instruction or
	Segmentation fault. intro-text,
	middle-text, and end-textare for the user's
	benefit and have no particular format.
^Z^Zsignal	The syntax of this annotation is just like signalled,
	but GDB is just saying that the program received
	the signal, not that it was terminated with it.
^Z^Zbreakpoint number	The program hit breakpoint number number.
^Z^Zwatchpoint number	The program hit watchpoint number number.

20.11 Displaying source

The following annotation is used instead of displaying source code:

^Z^Zsource filename:line:character:middle:addr

where filename is an absolute file name indicating which source file, line is the line number within that file (where 1 is the first line in the file), character is the character position within the file (where 0 is the first character in the file, for most debug formats this will necessarily point to the beginning of a line), middle is `middle' if addr is in the middle of the line, or `beg' if addr is at the beginning of the line, and addr is the address in the target program associated with the source which is being displayed. addr is in the form `0x' followed by one or more lowercase hex digits (note that this does not depend on the language).
