==英文原文==CloseThreadpoolIo Function
Releases the specified I/O completion object.
Syntax
C++
VOID WINAPI CloseThreadpoolIo(
__inout PTP_IO pio
);
Parameters
pio [in, out]
A TP_IO structure that defines the I/O completion object. The CreateThreadpoolIo function returns this structure.
Return Value
This function does not return a value.
Remarks
The I/O completion object is freed immediately if there are no outstanding callbacks; otherwise, the I/O completion object is freed asynchronously after the outstanding callbacks complete.
You should close the associated file handle and wait for all outstanding overlapped I/O operations to complete before calling this function—you must not cause any more overlapped I/O operations to occur after calling this function.
To compile an application that uses this function, define _WIN32_WINNT as 0x0600 or higher.
Requirements
