IMailMsgProperties::GetContentSize

Platform SDK: SMTP Server Events

[This is preliminary documentation and subject to change.]

Get the current MailMsg content size in bytes with optional asynchronous completion.

HRESULT GetContentSize(
   [out] DWORD *pdwSize,
   [in,unique] IMailMsgNotify *pNotify
);

pdwSize: Receives the result.
pNotify: Interface to notify for asynchronous completion. If this value is NULL, then the operation will complete synchronously. Even if this value is non-NULL, the operation may still complete synchronously (i.e. it may return S_OK instead of MAILMSG_S_PENDING).

Value	Description
S_OK	Success. The operation completed synchronously.
MAILMSG_S_PENDING	Success. The operation is pending, and pNotify->Notify will be called with the result of the operation when it completes.
