This variable is set to non-nil when the
Run | CG Argument Checking
menu-item is toggled on, and to nil when the
menu-item is toggled off. When non-nil, each
call to an exported non-generic Common Graphics function will check
that the type of most arguments is valid. (Note that not all arguments
are checked.) This variable may be set or bound programmatically as
an alternative to using the menu command.
Toggling the argument checking on may be useful for finding bugs that are not otherwise obvious. Note that argument checking slows down some CG functionality significantly, though, so it is probably not desirable to leave CG argument checking on all the time.
