Contents

Return value
Returns the FCD items handle, suitable for traversal with the Tree API
Detailed description

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

- Declare a variable 'result' of type HANDLE
- Add to a calculation icon:
result = ::FCD.GetItemHandle(pathname, "itemname")
