C# Signature:
[DllImport("kernel32", SetLastError=true)]
static extern UInt32 WaitForSingleObject(IntPtr handle, Int32 milliseconds);
User-Defined Types:
None.
Notes:
None.
Tips & Tricks:
const UInt32 INFINITE = 0xFFFFFFFF;
const UInt32 WAIT_ABANDONED = 0x00000080;
const UInt32 WAIT_OBJECT_0 = 0x00000000;
const UInt32 WAIT_TIMEOUT = 0x00000102;
and use:
WaitForSingleObject(handle, (int)INFINITE);
Sample Code:
private void Run()
{
while (bRunning)
{
try
{
if(WaitForSingleObject(ReceivedEvent,INFINITE) == WAIT_OBJECT_0)
{
// Signaled
DoSomething();
}
}
catch(Exception Ex)
{
// An exception occurred
//
trhow(Ex);
}
}
}
UInt32 waitFor;
waitFor = WaitForSingleObject(hMutex, 10000);
if (waitFor == WAIT_TIMEOUT)
throw new ....
else if (waitFor == WAIT_ABANDONED)
{
ReleaseMutex(waitFor);
throw new ....
}
if (waitFor != WAIT_OBJECT_0)
{
throw new Win32Exception("Synchronization Mutex Error.");
}
return 0;
Alternative Managed API:
If you have a System.Diagnostic.Process object (possibly created by Process.Start), call Process.WaitForExit().
If you're waiting on a file system object, look at System.IO.FileSystemWatcher
System.Threading.WaitHandle and derivatives (e.g. AutoResetEvent)
