Andrew Johnson b7f8f17227 blockingSockTest: Undo member renames using m_ prefix 
Using the m_ prefix to denote class data members is dangerous in
code that has to compile on VxWorks 5.5 (which 3.15 does) because
the net/mbuf.h header contains the following macro definitions:

#define m_next          mBlkHdr.mNext
#define m_len           mBlkHdr.mLen
#define m_data          mBlkHdr.mData
#define m_type          mBlkHdr.mType
#define m_flags         mBlkHdr.mFlags
#define m_nextpkt       mBlkHdr.mNextPkt
#define m_act           m_nextpkt
#define m_pkthdr        mBlkPktHdr
#define m_ext           pClBlk
#define m_extBuf        m_ext->clNode.pClBuf
#define m_extFreeRtn    m_ext->pClFreeRtn
#define m_extSize       m_ext->clSize
#define m_extRefCnt     m_ext->clRefCnt
#define m_extArg1       m_ext->clFreeArg1
#define m_extArg2       m_ext->clFreeArg2
#define m_extArg3       m_ext->clFreeArg3
#define  m_copy(m, o, l)        m_copym((m), (o), (l), M_DONTWAIT)
#define  m_copym(m, o, l, w)    netMblkChainDup(_pNetDpool, (m), (o), (l), (w))
#define  m_freem(m)             netMblkClChainFree(m)
#define  m_free(m)              netMblkClFree(m)    
#define m_mbufs         mNum
#define m_drops         mDrops
#define m_wait          mWait
#define m_drain         mDrain
#define m_mtypes        mTypes

While the names in the original change all appear to be safe, I
don't want us to start using this convention because we will then
have to police commits more closely or risk build failures in the
future when someone who doesn't know about or remember the issue
can't or doesn't try building their code against VxWorks 5.5.

I don't particularly like the this-> convention to mark member
names either, but until the VxWorks 5.5 support requirement goes
away the m_ convention is worse. Another common convention of
using a leading underscore is not safe either, those names are
reserved for the C/C++ implementation.

Andrew Johnson 8d5cdc3747 Fix typo in macro name 
Not that it really matters since only VxWorks and RTEMS actually
compile this file and they don't have shared libraries...

Andrew Johnson 75da9fd454 Moved dlopen version of osdFindSymbol.c into posix 
It was identical in solaris, Darwin and Linux, and had
not been included for cygwin so this reduces duplication.

Michael Davidsaver 83dfc7980d thread pool: handle failure to create worker 
epicsJobQueue() returns EAGAIN when the first worker

Failure to create workers beyond the first is
silently ignored.

Michael Davidsaver 0bf17be9e3 mmio: vxWorks m68k use default, add weak symbols for old versions 2014-07-16 15:12:56 -04:00
Andrew Johnson 3ff49fc9b2 Fixed build errors, remove dependency on std. 
Build errors: Include guard missing from epicsUnitTest.h;
    dbShutdownTest.c was calling the non-universal strcasecmp()
    instead of epicsStrCaseCmp().

ioc/db/test no longer depends on std. I modified
    xRecord to make it a working record type, and simplified the
    other test programs so they all use the same new expanded
    dbd file rather than each making their own. I also added
    dbShutdownTest() to epicsRunDbTests().

Andrew JohnsonandMichael Davidsaver 60a0c7f181 Make epicsExit subsystem reusable. 
Calling epicsAtExit() after epicsExitCallAtExits() now
recreates the per-process list and registers the routine.

Jeff Hill johill@lanl.gov e374ee4658 patched this code to force alignment of the if request structure, which appears to be required to avoid exceptions on RTEMS with cpu architectures that detect use of misaligned addresses 2014-06-10 22:37:21 -06:00

add epicsSpinMustCreate()
