Hi, I am using SunOS4.1.1 and trying to open a file using the open system call with a mode value 777. Although my umask is 0, the file created has quite arbitrary permissions on it which causes an error the next time I try to open it. BTW the flags are O_WRONLY|O_CREAT|O_TRUNC. I also tried the creat system call with similar results. Any clue as to what am I missing? Please reply by e-mail. Thanx in advance Rumi Dubash rmd@geoquest.com rmdubash@cs.uh.edu ************************************************************************** Email: rmdubash@cs.uh.edu USMail: 5858 Westheimer #800 Houston, Tx 77057

Modes are expressed in octal. In C, 777 is decimal. 0777 is octal. There is no comp.unix.programmers group, by the way. ---Dan

If the bits *are* r----x--x, you're forgetting that the mode is generally written in octal, or else you're forgetting that octal isn't the default base for numbers in C. Try giving the mode value as 0777 instead of 777 and see if it doesn't help. der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu
