Releases the specified wait object.
void CloseThreadpoolWait( PTP_WAIT pwa );
A TP_WAIT structure that defines the wait object. The CreateThreadpoolWait function returns this structure.
The wait object is freed immediately if there are no outstanding callbacks; otherwise, the timer object is freed asynchronously after the outstanding callbacks complete.
If there is a cleanup group associated with the wait object, it is not necessary to call this function; calling the CloseThreadpoolCleanupGroupMembers function releases the work, wait, and timer objects associated with the cleanup group.
To compile an application that uses this function, define _WIN32_WINNT as 0x0600 or higher.
For an example, see Using the Thread Pool Functions.
