nCtlID

ID of the control that received the context sensitive help click. A value of -1 refers to the Help Button itself. For a list of other possible values, refer to the DLGRESID.H file in the LEAD \ INCLUDE directory.

pUserData

A 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. (This is the same pointer that you pass in the pUserData parameter of the calling function.)

Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
