3588.0. "new in signal handler?" by CHEFS::DAVIDSONS () Mon May 26 1997 19:34

    I understand it's not safe to use malloc within a signal handler
    but is it safe to use new within a signal handler?
    
    Thanks,
    	Stuart.

	The default implementation of 'new' calls 'malloc'. Peter.
3588.2	non malloc new?	CHEFS::DAVIDSONS		`Tue May 27 1997 19:26`	6
	Thanks. Does that imply that there's a version of new which would be safe to use in a signal handler? Stuart.
