New Revision: 345089
URL: https://svnweb.freebsd.org/changeset/base/345089
Log:
Some fixes for proccontrol(1) man page.
- Fix markup.
- Mention that process can only allow tracing for itself. This is already
stated in procctl(2), but requiring knowledge of the syscall description
is too much for the tool user.
- Clearly state that query mode only works for existing process.
