  WSD_HOST_METADATA** ppHostMetadata

Error code

Description

S_OK

This method completed successfully.

E_POINTER

ppHostMetadata is NULL.

Remarks

GetHostMetadata will not cause the device proxy to retrieve metadata from the device. Instead, GetHostMetadata will return the metadata retrieved with the last call to IWSDDeviceProxy::BeginGetMetadata and IWSDDeviceProxy::EndGetMetadata. If neither of these methods has been called, GetHostMetadata will return the metadata retrieved when the IWSDDeviceProxy object was initialized.

Upon success, the memory at ppMetadata will be valid until BeginGetMetadata or EndGetMetadata is called or until the IWSDDeviceProxy object is released.
