Update core library GPL boilerplate and (C) from git log 2019-08-03 15:53:17 +02:00
cf52d6e4b4 enough with umpteen "i18n.h" files. Consolidate on pbd/i18n.h 2016-07-14 14:45:23 -04:00
119e56e7eb Add PBD::QPC::initialize to initialize timer and call it from PBD::init
Check timer for invalid frequency
Precalculate timer tick rate to save a few instructions
Don't use static variables inside functions to avoid checking for initialization
Use static functions inside anonymous namespace for internal linkage

9bd893a6a2 Make sure the QPC frequency is cached so the timer can be used 2015-09-16 22:50:37 +10:00
f4cb4e479d Rename PBD::QPC::get_timer_valid to check_timer_valid and perform timer test
I'm not sure if this test is going to be effective as I don't have hardware to
test on at the moment. As noted in the documentation, Windows XP should be the
only OS where QPC uses a timer source that is non-monotonic(multi-core with
non-syncronized TSC).

a88b2da6a9 Fix PBD::MMTIMER::reset_resolution and add some documentation
timeEndPeriod must be called with the same timer resolution value used in
timeBeginPeriod. When the process exits the timer resolution is restored anyway
so this is not very important.
