16 This function is missing on some platforms:
19 The symbolic value @code{SIG_IGN} for the @code{SIGCHLD} signal is equivalent
22 void handle_child (int sigchld)
24 while (waitpid (-1, NULL, WNOHANG) > 0)
28 except that @code{SIG_IGN} for @code{SIGCHLD} has the effect that the children
29 execution times are not accounted in the @code{times} function.
30 On some platforms (BSD? SystemV? Linux?), you need to use the @code{sigaction}
31 flag @code{SA_NOCLDWAIT} in order to obtain this behavior.
