Adding a Child Branch
IVI-C drivers are arranged in a hierarchy of functions and attributes by managing two special files defined by the IVI specifications -- the function panel file (<prefix>.fp) and the attribute information file (<prefix>.sub). The exported functions and #define macros (for attributes) in the <prefix>.h file are simply a flat list from the client programmer's perspective. But, these .fp and .sub files are understood by various ADEs and can greatly simplify working with IVI-C driver APIs.
Nimbus uses the term branch to refer to a level of hierarchy an IVI-C driver.
From Solution Explorer, double-click the Driver Designer node under the Nimbus node.
The IVI-C Driver Designer tree view opens.
Expand the root node.
Right-click on the desired location within the hierarchy and choose Add Child Branch. You can add a new child branch directly below the root node or at any level in the hierarchy.
A new branch node is added with a default name and the tree node enters edit mode. Type the desired name for the branch and hit the Enter key.
