I'd missed your point earlier!!! I was calling pthread_join with the address
of the thread rather than the thread itself...
That's all I needed. My experience is very stale w/ C & C++, but why didn't I
get at least a compilation warning when I passed the reference to the thread,
rather than its value?
I.e.
pthread_t thread;
<snip>
retVal = pthread_join(thread, &threadExitStatus);
*AND*
pthread_t thread;
<snip>
retVal = pthread_join(&thread, &threadExitStatus);
both compile with no warnings or errors (using g++ -W -Wall
-Wno-non-virtual-dtor -Wwrite-strings -Wpointer-arith -Wnested-externs
-Woverloaded-virtual -Wbad-function-cast -ansi -pedantic).
