d_layerPurposeID
) 
=> l_value / nil

Description

Returns the list of attributes for the specified layer-purpose pair in the current technology database. The attributes (display priority, visibility, selectability, if the layer is visible when dragged, and validity) are defined in the techLayerPurposePriorities and techDisplays subsections of the ASCII technology file associated with the layer-purpose pair. If the layer-purpose pair does not exist, this function returns nil.
