Allow the NTP Time provider (used on VxWorks and RTEMS only)
to adapt to changes in the OS clock tick rate after the provider
has been initialized.
Changing the tick rate after iocInit() is not advisable,
other software might still misbehave if initialized before
an OS tick rate change.
Fix unchecked buffer allocation in dbChannel.c
Replace calls to epicsStrDup() with checked malloc() for
things that happen often after iocInit.
Michael Davidsaver pointed out this issue.
Fractional seconds could round-up to .000 without
incrementing the integer seconds.
We can't actually do the latter, so we prevent the
roll-over and clamp at all 9's instead.
Idea from Eric Norum.
VxWorks 6.x can make environment variables private to each
thread, which doesn't work too well.
A test failure on VxWorks explains how to change the image
configuration to fix this.
o suprressed some compile time warnings in bucketLib.c
o cleaned up cxx templates README
o removed use of tsMinMax from libCom in favor of the standard library
(calls to tsMinMax still exist in other components in base, but they are being removed)
o removed sharable library export of certain private member functions from class fdManager
o fixed aToIPAddr to correctly lookup all of the different IP addresses string types on all OS types
independent of the OS interfae variations
o removed use of inet_aton from vxWorks implementation of hostToIPAddr
o this function is for converting a host name to an ip address _only_
o the aToIPAddr wrapper is supposed to do the dotted ip ascii string to ip address structure
conversion independent of OS spoecific interface variations, when it works correctly
o fixed some spelling issues in comments
o added additional optimizations for processors w/o floating point ALU to addNanoSec in epicsTime
o removed tabs and junk comments from win32 osdProcess.c
o moved PLL update in win32 osdTime.c from timer to a dedicated thread
o added missing epicsExportShared symbols define to osiNTPTime.c
o fixed server ctor should not modify arguments of its caller in blockingSockTest
o removed sunpro specific ifdef nolomger needed from epicsTimeTest.cpp
Using idea from Peter Heesterman:
* Instanciate the alarm strings once in libCom
* Remove the epicsAlarmGlobal macro
* Make sure the decorations are right
From devLib2
adds calls to handle 8, 16, and 32 bit
Memory Mapped I/O reads and writes.
Adds X_iowriteY() and X_ioreadY().
where X is nat (native), be, or le.
Y is 16 or 32.
Also adds ioread8() and iowrite8().
* Implementation for posix and WIN32 tries to get the CPUs available for this process,
rather than the complete number of CPUs in the system.
* For the time being, vxWorks returns 1. (This will have to change for vxWorks SMP.)
Since Apple don't support clock_gettime(CLOCK_REALTIME) I added a
new time provider that uses the Mach kernel Clock service to get
nanosecond resolution time.
