New Revision: 280005
URL: https://svnweb.freebsd.org/changeset/base/280005
Log:
Define a convenience macro, SYSCTL_OUT_STR() for handling strings the
standard way (including the nulterm byte in the data returned to userland).
This augments the existing sysctl_handle_string() in that this can be used
with const strings without ugly inappropriate casting.
