InternetLockRequestFile Function

Allows the user to place a lock on the file that is being used.

Syntax

BOOL InternetLockRequestFile (
    IN HINTERNET hInternet,
    OUT HANDLE *lphLockReqHandle
);

Parameters

hInternet

HINTERNET handle returned by FtpOpenFile, GopherOpenFile, HttpOpenRequest, or InternetOpenUrl.

lphLockReqHandle

Address of a handle to store the lock request handle.

Return Value

Returns TRUE if successful, or FALSE otherwise. To get a specific error message, call GetLastError.

Remarks

If the HINTERNET handle passed to hInternet was created using INTERNET_FLAG_NO_CACHE_WRITE or INTERNET_FLAG_DONT_CACHE, the function creates a temporary file with the extension .tmp, unless it is an HTTPS resource. If the handle was created using INTERNET_FLAG_NO_CACHE_WRITE or INTERNET_FLAG_DONT_CACHE and it is accessing an HTTPS resource, InternetLockRequestFile fails.
