IFillLockBytes::SetFillSize (Windows CE 5.0)
This method sets the expected size of the byte array.
HRESULT SetFillSize(ULARGE_INTEGER uISize);
Parameters
- uISize
[in] Size in bytes of the byte array object that is to be filled in subsequent calls to IFillLockBytes::FillAppend.
Return Values
This function supports the standard return values E_OUTOFMEMORY, E_UNEXPECTED, E_INVALIDARG, and E_FAIL.
Remarks
If SetFillSize has not been called, any call to ILockBytes::ReadAt that attempts to access data that has not yet been written using IFillLockBytes::FillAppend or IFillLockBytes::FillAt will return a new error message, E_PENDING.
After SetFillSize has been called, any call to ReadAt that attempts to access data beyond the current size, as set by SetFillSize, returns E_FAIL instead of E_PENDING.
To determine whether the platform supports this interface, see Determining Supported COM APIs.
