Parameter	Description
hNet	A DICOM Network handle to the peer member of the connection.
nPresentationID	Presentation ID. The presentation ID provides information about both the class type of the data and the transfer syntax to use when transferring the data.
nMessageID	Message ID. Each message sent by a member of a connection should have a unique ID. Since a member of a connection may send several messages, this ID allows that member to identify when a specific request has been completed.
pszClass	Class affected by the request. This will be an SOP Class or an SOP MetaClass.
pszInstance	The instance of the class. A server may, for example, have three instances of the Nuclear Medicine Class. This value identifies the data with a specific instance.
nAction	An application specific action to be performed on the specified data set.
hDS	The data set on which the specified action is to be performed.
pUserData	Void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function.
	Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

None.
