Parameter Description
hNet A DICOM Network handle.
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.
nPriority The priority level of the message. The Service Class Provider may or may not support priority. Therefore, setting this parameter may or may not have any effect. Possible values are:
  Value Meaning
  COMMAND_PRIORITY_LOW [0x0002] Low priority message.
  COMMAND_PRIORITY_MEDIUM [0x0000] Medium priority message.
  COMMAND_PRIORTY_HIGH [0x0001] High priority message.
hDS Pointer to the data set to be found.
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.




A call to this function is generated on a peer member of a connection when L_DicomSendCFindRequest is called.

To use this callback function, RECEIVECFINDREQUESTCALLBACK must be set using L_DicomSetCallback.
