Detailed Description

definitions

You need to fill one of these in an pass it to the registration function. The values are copied so this doesn't have to survive once the registration call is done. So usually it's done as an automatic variable in the stack.

Make sure to use the right one for your variable type. See Variable types for what to use for the individual types.
