HP gnu source-level debugger 5992-4701 manual Functions whose names contain a match for, Again

info functions regexp	Print the names and data types of all defined
	functions whose names contain a match for
	regular expression regexp. Thus, 'info fun
	step' finds all functions whose names include
	step; 'info fun ^step' finds those whose
	names start with step.
info variables	Print the names and data types of all variables
	that are declared outside of functions (that is,
	excluding local variables).
info variables regexp	Print the names and data types of all variables
	(except for local variables) whose names contain
	a match for regular expression regexp.
	Some systems allow individual object files that
	make up your program to be replaced without
	stopping and restarting your program. For
	example, in VxWorks you can simply recompile
	a defective object file and keep on running. If you
	are running on one of these systems, you can
	allow GDB to reload the symbols for
	automatically relinked modules:
	set	Replace symbol definitions
	symbol-reloadingfor the corresponding source
	on	file when an object file with
		a particular name is seen
		again.
	set	Do not replace symbol
	symbol-reloading	definitions when
	off	encountering object files of
		the same name more than
		once. This is the default

state; if you are not running on a system that permits automatic relinking of modules, you should leave symbol-reloading off, since otherwise GDB may discard symbols when linking large programs, that may contain several modules (from different directories or libraries) with the same name.
