[rlug] Re: pty question

[Ionut Spirlea]

salut,


i-am adus io modificari. (man wait)

#include <stdio.h>
#include <pty.h>
#include <unistd.h>
#include <signal.h>
#include <sys/wait.h>

void sigchld_handler(int chld)
{
        while(waitpid(-1, &chld, WNOHANG) > 0 );
}

int main()
{
        int master, pid;

        signal(SIGCHLD, sigchld_handler);

        if  ((pid=forkpty(&master, NULL, NULL, NULL))==-1) {
                perror("forkpty()");
        }
        if (!pid) {
                sleep(1); return 0;
        } else sleep(2);
        close(master);
        printf("asta e\n");
        getchar();
        return 0;
}
