"Before the specified function is executed, the value of func is set to SIG_DFL. The next interrupt signal is treated as described for SIG_DFL, unless an intervening call to signal specifies otherwise. This feature lets you reset signals in the called function." That's good enough (well not really *good*, but *enough*) to know how to implement signal handling on missing-sigaction platforms.
