<sidebar>API Contents</sidebar> Gets a FCD items handle, suitable for traversal with the Tree API
Contents
Parameters
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
Return value
Returns the FCD items handle, suitable for traversal with the Tree API
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")
No additional examples
