Hi nelson,
i remeber a problem i got long time ago with openthreads and windows, even
on a 32 bit system. i located that we go an issue on windows system with the
sleep method. (windows native).
so can you try following:
(1) replace the microsleep with the
OpenThreads::Thread::YieldCurrentThread()
report what happens
(2) replce the microsleep only in the Thread class / method with
YieldCurrentThread
report what happens
if both test are also negative, then replace microsleep with
void millisleep( unsigned int milliseconds )
{
# ifdef _MSC_VER // If its Visual C++ call Win32 Sleep function
::Sleep( milliseconds);
#else // Else assume a UNIX/Linux system with nanosleep function
timespec ts;
ts.tv_sec = milliseconds / 1000;
ts.tv_nsec = (milliseconds - ts.tv_sec*1000) * 1000000;
::nanosleep(&ts, NULL);
# endif
}
what happens ?
Have also a look into:
and search in google with adrian egli / openthreads / sleep
