Include file

Pdce.bdh

Syntax

PdceGetMeasureValue( in  hMeasure     : number,
                     in  sMeasureName : string,
                     in  nScaleFactor : number optional,                   
                     out fValue       : float optional ): boolean

Return value

true if successful
false otherwise

Parameter	Description
hMeasure	Specifies the measure's handle, from the `PdceMeasureSubscribe` or `PdceAddMeasure` function.
sMeasureName	Specifies the name for the custom counter where the last queried value is stored in.
nScaleFactor	Optional scale factor by which the retrieved value is divided.
fValue	Optional floating point value which is set to the current value.
