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. |
pnAttribute |
An array of the attributes to get. The attributes must be specified using the Data Element Tags. For a list of available Data Element Tags, refer to Data Element Tag Constants. |
nCount |
Number of attributes being requested. |
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.
Comments
