#5594 closed Bugs (fixed)

boost::shared_mutex not fully compatible with Windows CE.

Reported by: Oscar E. Lara <oscar.lara@…> Owned by: viboes
Milestone: Boost 1.49.0 Component: thread
Version: Boost 1.46.1 Severity: Problem
Keywords: Cc:

Description

Found that shared_mutex for Win32 is using the function WaitForMultipleObjects. MSDN specifies clearly that the argument fWaitAll must be FALSE, however the current version of the file shared_mutex.hpp is ussing the call as followed:

unsigned long const wait_res=detail::win32::WaitForMultipleObjects(2,semaphores,true,::boost::detail::get_milliseconds_until(wait_until));

This failure gets reflected in Boost assertion and/or slow system. The frequency of the failure depends on the number of threads and the timings.

MSDN for WaitForMultipleObjects under Windows CE 6.0 can be found ​http://msdn.microsoft.com/en-us/library/aa915354.aspx.
