Synopsis

- data StgInfoTable = StgInfoTable {
  - entry :: Maybe EntryFunPtr
  - ptrs :: HalfWord
  - nptrs :: HalfWord
  - tipe :: ClosureType
  - srtlen :: HalfWord
  - code :: Maybe ItblCodes
  }
- type EntryFunPtr = FunPtr (Ptr () -> IO (Ptr ()))
- type HalfWord = Word32
- type ItblCodes = Either [Word8] [Word32]

# Documentation

data StgInfoTable #

This is a somewhat faithful representation of an info table. See https://gitlab.haskell.org/ghc/ghc/blob/master/rts/include/rts/storage/InfoTables.h for more details on this data structure.
