interesting open() issue

[Foldi Tamas]

Hello hackers,

        I tried the following program on Tru64, FreeBSD and linux:

#include <stdio.h>
#include <fcntl.h>
#include <sys/stat.h>
#include <sys/types.h>
main() {  
        int fd;
        fd = open ( "/tmp/foobar", (O_RDWR | O_CREAT),  0020);
        perror("open");
        close(fd);
}

The program ran successfully, but the created file was different. 
On Linux:
    -----w----    1 crow     crow            0 Jan 16 10:32 /tmp/foobar

On Tru64/FreeBSD:
    ----------    1 crow     users           0 Jan 16 10:30 /tmp/foobar

I'm not sure what the result supposed to be. Any ideas ?

Best Regards,
Tamas Foldi
