[Bambo AT bambo-notebook 4.4.4]$ cat tvfork.c
#include <sys/types.h>
#include <unistd.h>
#include <stdio.h>

int main(void)
{
        pid_t pid = vfork();
        if ( pid > 0 )
        {
                printf("I'm chield.\n");
                _exit(0);
        }
        else if ( pid == 0 )
        {
                printf("I'm parent");
        }
        else
        {
                perror("vfork failed.");
        }
}
[Bambo AT bambo-notebook 4.4.4]$ make tvfork
cc     tvfork.c   -o tvfork
[Bambo AT bambo-notebook 4.4.4]$ ./tvfork.exe
      4 [main] tvfork 4136 fork: child -1 - CreateProcessW failed, errno 2
vfork failed.: No such file or directory
[Bambo AT bambo-notebook 4.4.4]$ ./tvfork
      3 [main] tvfork 2956 fork: child -1 - CreateProcessW failed, errno 2
vfork failed.: No such file or directory

I think maybe the wrong parameters were sent while calling CreateProcessW.
