    change argv[0] after fork

    can someone tell me how can I change the name of a process after a for();
    normally it's done by changing argv[0], but how should it be done in a new process ?

    I'd suppose that it should work the same way in the new process as it does in the old process. The forked process gets its own copy of argv[].
    Insert obnoxious but pithy remark here

    Maybe you could do something like this

    #include <stdio.h>
    int main(int argc, char *argv[])
        argv[0] = "vvvv";
        printf("%s\n", argv[0]);    
        return 0;
