The string comparison functions epicsStrCaseCmp() and
epicsStrnCaseCmp() were returning incorrect results
when the strings did not match.
These functions now match their BSD equivalents, and
have working tests to confirm their operation.
Xiaoqiang Wang proposed some fixes that allow static builds on
the MinGW targets to succeed. Some additional changes made to
blockingSockTest.cpp also clean that up.
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.
Hostnames that begin with one or more digits were not being looked up
by name, causing problems at BNL.
This commit also changes the vxWorks implementation of hostToIPAddr()
to use inet_aton() instead of inet_addr().
Remove C++-isms.
Make internal routines static when duplicate names appear
in the epicsMutexTest.cpp code; on vxWorks and RTEMS all
test programs get linked into a single binary.
The strtoul() routine accepts negative numbers. This fix
ensures we handle them properly, and adds suitable tests.
Also fix the test for 1e300, in case the compiler gives a
slightly different literal constant than strtod() returns.
This lets us use epicsParseDouble() for scan rate parsing.
Ensure the scanOnce thread is a higher priority than the fastest
periodic scan thread, irrespective of how many threads there are.
Adds new routines for converting numeric strings into the
standard epicsInt8, epicsUInt8, epicsInt16, epicsUInt16,
epicsInt32 and epicsUInt32 types, along with Long, ULong,
Double and Float. These all provide error checking and
detection of extraneous characters. The epicsScanDouble
and epicsScanFloat routines originally in epicsStdlib.h
are replaced by macros that call the epicsParse routine,
and this also provides epicsScanLong and epicsScanULong
to match.
A test file is added to ensure conversions work properly
and report appropriate errors. This file also checks the
native strtod() routine if not used to check whether the
epicsStrtod() code is required on this platform.
