POSIX says it's supposed to be safe: "As it bypasses the usual function call and return mechanisms, longjmp() shall execute correctly in contexts of interrupts, signals, and any of their associated functions. However, if longjmp() is invoked from a nested signal handler (that is, from a function invoked as a result of a signal raised during the handling of another signal), the behavior is undefined." _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
