RoGetBufferMarshaler function (robuffer.h)
Provides a standard IBuffer marshaler to implement the semantics associated with the IBuffer interface when it is marshaled.
Syntax
HRESULT RoGetBufferMarshaler(
[out] IMarshal **bufferMarshaler
);
Parameters
[out] bufferMarshaler
pointer to Windows Runtime IBuffer marshaler
Return value
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
Provided for Windows Runtime language projections.
Custom IBuffer implementations are expected to be marshaled so that the remote instance eventually copies its contents back to the original instance. The IMarshal implementation provided by this method handles the copy by marshaling the current value of the IBuffer and specifying a platform-provided unmarshal COM class that creates an instance with identical IBuffer contents, length, and capacity.
The IMarshal implementation clones its contents to the original instance when the caller sets the Length property.
