[17:04:22] <awallin_> is there a complete list of numbered parameters somewhere? this list is very short: http://linuxcnc.org/docs/2.4/html/gcode_overview.html#sub:Numbered-Parameters
[17:15:55] -!- cjdavis1 has quit [Ping timeout: 240 seconds]
[17:17:23] <jepler> the 2.5 docs have a longer list, but I have no idea which ones (if any) apply to 2.4. http://www.linuxcnc.org/docs/2.5/html/gcode/overview.html#_numbered_parameters_a_id_sub_numbered_parameters_a
[17:18:14] <GoSebGo> Lol, thats a great anchor name
[17:18:54] <jepler> the ones pertaining to the g5x offsets are here in the 2.4 docs: http://linuxcnc.org/docs/2.4/html/gcode_main.html#sub:G54-to-G59.3:
[17:19:44] <jepler> dunno where the ones about the g92 offset are hiding, didn't find those yet :-P

[22:02:33] <jepler> .. that overflow is as old as the hills.
[22:02:56] <jepler> I suspect it's an invariant that inifile.Find will return something shorter than LINELEN, but it's an invariant that it's worth not assuming
[22:04:30] <jepler> + r = snprintf(mhz_str, sizeof(mhz_str), "%d.%03d", freq_mhz, freq_mhz_fractional);
[22:04:34] <jepler> + rtapi_snprintf(unknown, sizeof(unknown), "(unknown-gtag-%d)", gtag);
[22:05:06] <jepler> hm, I wonder if we document anywhere when to choose rtapi_snprintf and when to choose snprintf
[22:14:03] -!- FinboySlick has quit [Quit: Leaving.]
[22:14:15] <jepler> in realtime code you'd have to call rtapi_snprintf, and if you want the float formatting (such as it is) you'd also have to use it
[22:14:29] <jepler> the kernel snprintf should be fine for setup/teardown and may otherwise be a more complete implementation
