VarId
[in] ID of the Variable to get the name of.

Variable names consist of letters, numbers, and the underscore. All other characters are not permitted.
GetVariablePersist ( VarId )
Returns the persistence status of a Variable.
Syntax
HRESULT GetVariablePersist(
[in] long VarId,
[out, retval] long* Persist
);
Parameters
VarId
[in] ID of specified variable.
Persist
[out, retval] Returns 1 if the variable is persistent, and 0 if it is not.
Remarks
When a Variable is persistent, the value of the variable is stored to permanent storage after each time it is changed. So, if the
device is reset or the power is turned off, the Variable will still have its last value when the system restarts.
If the variable is not persistent, then the Variable’s value is set to its default whenever the system restarts.
