Porting WaitForSingleObject to Linux – Part 2

In my last post I discussed the use of WaitForSingleObject in relation to mutexes and possible ways to implement equivalent functionality when porting such code to GNU/Linux.  In this post I will describe the use of this API with event objects in Microsoft Windows and suggest possible ways of posting such code to GNU/Linux or Unix. First, some background on event objects.  An event object is just another type of Windows kernel dispatcher object.  From a coding prespective, an event object is a synchronization object which encapsulates one or more kernel dispatcher objects and whose synchronization semantics are accessable via

Porting WaitForSingleObject to Linux – Part 1

Recently I was involved in porting a 32-bit application which was initially written for Microsoft Windows NT to GNU/Linux.  This application contained a large number of calls to NtWaitForSingleObject and a smaller number of calls to NtWaitForMultipleObject.  Now anybody who has had to port code containing more than a few instances of these particular Win32 APIs, or their close cousins WaitForSingleObjectEx, MsgWaitForMultipleObjects, MsgWaitForMultipleObjectsEx, etc. to Unix or GNU/Linux is probably already shuddering with the recollection of long arduous days and nights of trial and error coding to try and correctly mimic the semantics and functionality of these particular Microsoft Windows
