WNNC_RESOURCE
Returns a mask of bit values that indicate specific behaviors of the NP and its underlying network. These behaviors are used by the MPR to provide intelligent processing for the NP. For example, if a network does not support deviceless connections, the MPR knows how to select a local when making connections.
WNNC_RES_VALIDLOCALDEVICE
These values have the following meanings:
WNNC_RES_VALIDLOCALDEVICE means that the NP has restrictions upon valid local device names (for example, only supporting "LPT1" to "LPT3" when the Windows 95 printing system supports more printer numbers). The NP must export NPValidLocalDevice if it sets this value.
