You can accomplish this without writing to the file system, but it involves foregoing NSTask. Fork, close stdin in the child process, open a pipe (so that the child gets the read end in fd 0), then exec the tool with "/dev/stdin" as the filename argument. I'm not sure it's any more secure than just writing to the filesystem, though. It depends on whether OS X lets a user view the memory of other processes running as that user. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
