* Instead of an error string, return the usual 0 or -1 and let the caller figure out what, if anything, to tell the user. * Avoid string manipulations by opening /dev first and using openat() with O_RESOLVE_BENEATH. * Add a boolean argument which, if false, causes ttymsg() to return without sending the message if the tty's group-writable bit is not set. This saves programs that respect this setting (like syslogd(8)) from having to check before calling ttymsg(). * Update all callers. The observable effect of this change is minimal except for slightly different error messages when ttymsg() fails. However, syslogd(8) will no longer print spurious error messages on the console after trying and failing to write a log message to an X11 session.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
