GHCi.InfoTable

Description

Run-time info table support. This module provides support for creating and reading info tables in the running program. We use the RTS data structures directly via hsc2hs.

Synopsis

peekItbl :: Ptr StgInfoTable -> IO StgInfoTable
data StgInfoTable = StgInfoTable {
- entry :: Maybe EntryFunPtr
- ptrs :: HalfWord
- nptrs :: HalfWord
- tipe :: HalfWord
- srtlen :: HalfWord
- code :: Maybe ItblCodes
}
conInfoPtr :: Ptr () -> Ptr ()
mkConInfoTable :: Int -> Int -> Int -> Int -> [Word8] -> IO (Ptr StgInfoTable)

Convert a pointer to an StgConInfo into an info pointer that can be used in the header of a closure.
