This method reads data retrieved by the pluggable protocol handler.
Syntax
HRESULT Read( void* pv, ULONG cb, ULONG* pcbRead ); |
Parameters
- pv
-
[in, out] Address of the buffer where the information will be stored.
- cb
-
[in] ULONG value that indicates the size of the buffer.
- pcbRead
-
[out] Address of a ULONG value that indicates the amount of data stored in the buffer.
Return Value
Returns one of the values shown in the following table.
Value | Description |
