InternetCloseHandle (Windows CE 5.0)
This function closes a single Internet handle or a subtree of Internet handles.
BOOL WINAPI InternetCloseHandle(HINTERNEThInternet);
Parameters
- hInternet
[in] Valid Internet handle to be closed.
Return Values
TRUE indicates success. FALSE indicates failure. To get extended error information, call GetLastError.
Remarks
This function terminates pending operations on the handle and discards outstanding data. If a thread is blocking a call to Wininet.dll, another thread in the application can call InternetCloseHandle on the Internet handle being used by the first thread to cancel the operation and unblock the first thread.
If there is a status callback registered for the handle being closed and the handle was created with a non-NULL context value, an INTERNET_STATUS_HANDLE_CLOSING callback will be made. This indication will be the last callback made from a handle and indicates that the handle is being destroyed.
If asynchronous requests are pending for the handle or any of its child handles, the handle cannot be closed immediately, but it will be invalidated. Any new requests attempted using the handle will return with an ERROR_INVALID_HANDLE notification. The asynchronous requests will complete with INTERNET_STATUS_REQUEST_COMPLETE. Applications must be prepared to receive any INTERNET_STATUS_REQUEST_COMPLETE indications on the handle before the final INTERNET_STATUS_HANDLE_CLOSING indication is made, which indicates that the handle is completely closed.
An application can call GetLastError to determine if requests are pending. If GetLastError returns ERROR_IO_PENDING, there were outstanding requests when the handle was closed.
Requirements
OS Versions: Windows CE 2.0 and later.
Header: Wininet.h.
