* src/mqueuesendsupp.c: Account for possibly blocking during the
core send operation.
2001-08-16 Joel Sherrill <joel@OARcorp.com>
* src/msgqsubmit.c: Add a comment indicating that we do not have
to account for possibly blocking during the core send operation
because Classic API message queue send is always non-blocking.
2001-08-16 Joel Sherrill <joel@OARcorp.com>
* include/rtems/score/coremsg.h, src/coremsgsubmit.c: Add a new
return status to account for blocking sends. Otherwise, the
caller will think that the returned message status will have
the ultimate results of the operation. If the send times out,
the final status will be in the return_code of the thread.
2001-08-16 Joel Sherrill <joel@OARcorp.com>
* src/coremutexsurrender.c: Use holder thread not executing
thread because even though they may and often are the same
it is not guaranteed unless the proper attribute is set.
2001-08-16 Joel Sherrill <joel@OARcorp.com>
* startup/linkcmds: Modified to work better with gcc 2.8.1 and
gnat 3.13p.
2001-08-16 Joel Sherrill <joel@OARcorp.com>
* tools/runtest.in: Recognize debug variant of monitor test.
2001-08-16 Joel Sherrill <joel@OARcorp.com>
* sp13/sp13.scn: Id in screen had wrong class field value.
* sp13/system.h: Account for message buffer memory.
* sp13/task2.c: Remove unnecessary check for failure.
2001-08-16 Joel Sherrill <joel@OARcorp.com>
* sp20/system.h: Account for extra task stacks properly.
2001-08-16 Joel Sherrill <joel@OARcorp.com>
* include/tmacros.h: Attempt to print errno as further information.
