Re: [MacPerl] SYSOPEN

[Mark Manning/Simulacron I <markem@flash.net>]

O_RDWR and O_CREAT are from C.  Under Unix (and probably other OSs too)
there are certain commands which you can use to read from, write to, or
append information onto files.  On the Silicon Graphics Inc. (SGI)
computers using SGI's Unix variant you have:


     O_RDONLY
            Open for reading only.

     O_WRONLY
            Open for writing only.

     O_RDWR Open for reading and writing.

(I probably should have just said to look it up in the C manual - but I
do not know if you have such a thing.)

Anyway, this is an exerpt from the man pages on this.
