This property lets you modify the handling of SIGCHLD for this call. It will be reset afterwards.

It can be set to default, by the expression sig.dfl(), set to ignore with sig.ign() or assigned a custom handler. A custom handler must have the type sighandler_tand can be assigned with the following syntax:

sig = handler;
sig(handler);
