	GetItemHandle
Gets a FCD items handle, suitable for traversal with the Tree API
- HANDLE	PathName
An existing handle or the '.' separated path through the FCD to look in
- STRING	ItemName
The name of an item in the path to find
- HANDLE	Return

Detailed description

This will get a handle suitable for traversal by the Tree API which is a collection of functions suitable for traversing the FCD files.

FCD files are XML files. The PathName must be a list of items, not including the XML root tag of the tags where the XML attribute ItemName is to be located. So to extract a handle to the FLASH memory size Pathname="device.memory" and ItemName="bytes".

If the ItemName is not found in the specified location then a 0 handle is returned.

Examples

Calling in a calculation

Declare a variable 'result' of type HANDLE

Add to a calculation icon:

result = ::FCD.GetItemHandle(pathname, "itemname")
