Reads the cached data from a stream that has been opened using the RetrieveUrlCacheEntryStream function.

Syntax

BOOLAPI ReadUrlCacheEntryStream(
  __in     HANDLE hUrlCacheStream,
  __in     DWORD dwLocation,
  __inout  LPVOID lpBuffer,
  __inout  LPDWORD lpdwLen,
  __in     DWORD dwReserved
);

Parameters

hUrlCacheStream [in]

Handle that was returned by the RetrieveUrlCacheEntryStream function.

dwLocation [in]

Offset to be read from.

lpBuffer [in, out]

Pointer to a buffer that receives the data.

lpdwLen [in, out]

Pointer to a variable that specifies the size of the lpBuffer buffer, in bytes. When the function returns, the variable contains the number of bytes copied to the buffer, or the required size of the buffer, in bytes.

dwReserved [in]

This parameter is reserved and must be 0.

Return Value

Returns TRUE if successful, or FALSE otherwise. To get extended error information, call GetLastError.

Remarks

If the buffer size is not sufficient, GetLastError returns ERROR_INSUFFICIENT_BUFFER and sets lpdwLen to the size necessary to contain all the information.
