    if ((pid = fork())  < 0) {
        perror("Fehler beim forken des Prozesses");
        exit(EXIT_FAILURE);
    } else if (pid == 0) {
        socket = connectToClient(config.hostname, config.portNumber);
        performHandshake(socket, gameId, spielerAnzahl);
        close(socket);
    } else {
        // implement me
    }

hi guys so i ive read abit the man page. If fork() returns 0 im in the child process and if it returns > 0 than im in the parent process (it returns the pid of the child process there)

Does the child process never know its own pid?

The child process can call getpid to get its pid

!man getpid

[polar lily]

man7

getpid(2)

getpid, getppid - get process identification

Synopsis

#include <unistd.h>

pid_t getpid(void);
pid_t getppid(void);

[crisp smelt]

it can also use getppid to get the parent pid
