IFillLockBytes::SetFillSize (Compact 2013)

3/26/2014

This method sets the expected size of the byte array.

Syntax

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 Value

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.
