The table below lists entrypoints which NPs may export, and their ordinals. NPGetCaps must be exported by name. Its presence is used by the MPR to identify a DLL as a valid NP. All other NP entrypoints are loaded by the MPR using their ordinals. An NP may export those entrypoints by ordinal only in order to reduce the size of the NP DLL file.
