Hi

Is it possible to implement threads in FreeBSD 4.0 kernel using the rfork
system call? If yes, could you give an example?


I tried to get the following piece of code to work without success.

#include <unistd.h>
main()
{
        if (rfork( RFPROC | RFNOWAIT | RFMEM | RFSIGSHARE ) > 0)
        {
                while(1)
                        printf ("Parent process's pid = %d\n", getpid());
        }
        while(1)
                printf ("Child process's pid = %d\n", getpid());
}

Regards
Satya
