IMarshalingStream::GetMarshalingContextAttribute method (objidl.h)
Gets information about the marshaling context.
Syntax
HRESULT GetMarshalingContextAttribute(
[in] CO_MARSHALING_CONTEXT_ATTRIBUTES attribute,
[out] ULONG_PTR *pAttributeValue
);
Parameters
[in] attribute
The attribute to query.
[out] pAttributeValue
The value of attribute.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
Each possible value of the attribute parameter is paired with the data type of the attribute this identifies.
You can query the following attributes with this method.
| Attribute | Values |
|---|---|
| CO_MARSHALING_SOURCE_IS_APP_CONTAINER | This attribute is a boolean value, with 0 representing TRUE and nonzero representing FALSE. You can safely cast the value of the result to BOOL, but it isn't safe for the caller to cast a BOOL* to ULONG_PTR* for the pAttributeValue parameter, or for the implementation to cast pAttributeValue to BOOL* when setting it. |
