2016-10-30Implement "dmesg -w".Elliott Hughes
Annoyingly, this means writing a new dmesg implementation that uses /dev/kmsg rather than the klogctl system call. Worse, pre-3.5 kernels don't support that, so we need to keep the old implementation around as long as we still care about those kernels. Since I'm here, add the fancy colors from modern dmesg and the -C flag. Tested on Nexus 9's 3.10 kernel, an Ubuntu 3.13 kernel, and the Nexus One's 2.6.35 kernel.
2015-05-03Fix dmesg -c error output.Elliott Hughes
Use perror_exit to show the likely "Operation not permitted" if klogctl fails.

2014-11-25Update dmesg, loosely based on a patch from Elliott Hughes.Rob Landley
Probe the default buffer size, replace the constants with FLAG_x macros, add -r, replace the byte at a time output with a single xwrite(), more comments.
2012-11-13Reindent to two spaces per level. Remove vi: directives that haven't worked ↵Rob Landley
right in years (ubuntu broke its' vim implementation). Remove trailing spaces. Add/remove blank lines. Re-wordwrap in places. Update documentation with new coding style. The actual code should be the same afterward, this is just cosmetic refactoring.
2012-10-08New build infrastructure to generate FLAG_ macros and TT alias, #define ↵Rob Landley
FOR_commandname before #including toys.h to trigger it. Rename DEFINE_GLOBALS() to just GLOBALS() (because I could never remember if it was DECLARE_GLOBALS). Convert existing commands to use new infrastructure, and replace optflag constants with FLAG_ macros where appropriate.
