GetPathHandle |
| Gets a FCD paths handle, suitable for traversal with the Tree API | |
 - STRING
|
PathName |
| The '.' separated path through the FCD to look in | |
 - HANDLE
|
StartPoint |
| The handle of an existing FCD path to start the search | |
| - 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 attributes are located. So to extract a handle to the FLASH memory detailes Pathname="device.memory".
If the StartPoint is provided then it is assumed this is a handle to a previous call to GetPathHandle, and this path is prepended to PathName. So if StartPoint is a handle to "device.configuration" and PathName="settings.setting" then the full path found will be "device.configuration.settings.setting".
Examples
Calling in a calculation
- Declare a variable 'result' of type HANDLE
- Add to a calculation icon:
result = ::FCD.GetPathHandle("pathname", startpoint)
