Daniel P. Berrange	3ec1289896	Add internal APIs for dealing with time ... The logging APIs need to be able to generate formatted timestamps using only async signal safe functions. This rules out using gmtime/localtime/malloc/gettimeday(!) and much more. Introduce a new internal API which is async signal safe. virTimeMillisNowRaw replacement for gettimeofday. Uses clock_gettime where available, otherwise falls back to the unsafe gettimeofday virTimeFieldsNowRaw replacements for gmtime(), convert a timestamp virTimeFieldsThenRaw into a broken out set of fields. No localtime() replacement is provided, because converting to local time is not practical with only async signal safe APIs. virTimeStringNowRaw replacements for strftime() which print a timestamp virTimeStringThenRaw into a string, using a pre-determined format, with a fixed size buffer (VIR_TIME_STRING_BUFLEN) For each of these there is also a version without the Raw postfix which raises a full libvirt error. These versions are not async signal safe * src/Makefile.am, src/util/virtime.c, src/util/virtime.h: New files * src/libvirt_private.syms: New APis * configure.ac: Check for clock_gettime in -lrt * tests/virtimetest.c, tests/Makefile.am: Test new APIs	2011-11-30 11:43:49 +00:00
