Re: [CPROG] signaler og SIGCHILD

Du kan eventuelt lade din handler for SIGCHLD gøre noget ala følgende:

voin handle_sigchld(int signum) {
    int* status;
    pid_t pid;

    /* Collect all terminated childrens */
    while(pid = waitpid(-1, status, WNOHANG) {}
} 

Det er ikke efterprøvet, og der skal måske også lige lidt ekstra
fejlhåndtering til.
