  1. readWord8X64Array# :: MutableByteArray# d -> Int# -> State# d -> (# State# d, Word8X64# #)

    base GHC.Base

    Read a vector from specified index of mutable array. Warning: this is only available on LLVM and can fail with an unchecked exception.

  2. readWord8X64OffAddr# :: Addr# -> Int# -> State# d -> (# State# d, Word8X64# #)

    base GHC.Base

    Reads vector; offset in bytes. Warning: this is only available on LLVM and can fail with an unchecked exception.

  3. readWordArray# :: MutableByteArray# d -> Int# -> State# d -> (# State# d, Word# #)

    base GHC.Base

    Read a word-sized unsigned integer; offset in machine words. Warning: this can fail with an unchecked exception.

  4. readWordOffAddr# :: Addr# -> Int# -> State# d -> (# State# d, Word# #)

    base GHC.Base

    Read a word-sized unsigned integer; offset in machine words. On some platforms, the access may fail for an insufficiently aligned Addr#. Warning: this can fail with an unchecked exception.

  5. readTVar :: TVar a -> STM a

    base GHC.Conc

    Return the current value stored in a TVar.

  6. readTVarIO :: TVar a -> IO a

    base GHC.Conc

    Return the current value stored in a TVar. This is equivalent to

    readTVarIO = atomically . readTVar
    
    but works much faster, because it doesn't perform a complete transaction, it just reads the current value of the TVar.

  7. readTVar :: TVar a -> STM a

    base GHC.Conc.Sync

    Return the current value stored in a TVar.

  8. readTVarIO :: TVar a -> IO a

    base GHC.Conc.Sync

    Return the current value stored in a TVar. This is equivalent to

    readTVarIO = atomically . readTVar
    
    but works much faster, because it doesn't perform a complete transaction, it just reads the current value of the TVar.

  9. readAddrArray# :: MutableByteArray# d -> Int# -> State# d -> (# State# d, Addr# #)

    base GHC.Exts

    Read a machine address; offset in machine words. Warning: this can fail with an unchecked exception.

  10. readAddrOffAddr# :: Addr# -> Int# -> State# d -> (# State# d, Addr# #)

    base GHC.Exts

    Read a machine address; offset in machine words. On some platforms, the access may fail for an insufficiently aligned Addr#. Warning: this can fail with an unchecked exception.
