getThreadId :: ThreadId# -> CInt

spark :: MonadPrim s m => a -> m a

numSparks :: MonadPrim s m => m Int

runSparks :: MonadPrim s m => m ()

delay :: MonadPrim s m => Int -> m ()

Wrapper for delay#. Sleep specified number of microseconds. Not designed for threaded runtime: Errors when compiled with -threaded

waitRead :: MonadPrim s m => Fd -> m ()

Wrapper for waitRead#. Block and wait for input to become available on the Fd. Not designed for threaded runtime: Errors when compiled with -threaded

waitWrite :: MonadPrim s m => Fd -> m ()

Wrapper for waitWrite#. Block and wait until output is possible on the Fd. Not designed for threaded runtime: Errors when compiled with -threaded

fork :: MonadPrim RW m => m () -> m ThreadId

Wrapper around fork#. Unlike forkIO it does not install any exception handlers on the action, so you need make sure to do it yourself.

forkOn :: MonadPrim RW m => Int -> m () -> m ThreadId

Wrapper around forkOn#. Unlike forkOn it does not install any exception handlers on the action, so you need make sure to do it yourself.

killThread :: MonadPrim RW m => ThreadId -> m ()

Wrapper around killThread#, which throws ThreadKilled exception in the target thread. Use throwTo if you want a different exception to be thrown.

yield :: MonadPrim RW m => m ()

Wrapper around yield#.

myThreadId :: MonadPrim RW m => m ThreadId

Wrapper around myThreadId#.

labelThread :: MonadPrim RW m => ThreadId -> Ptr a -> m ()

Pointer should refer to UTF8 encoded string of bytes

isCurrentThreadBoundPrim :: MonadPrim RW m => m Bool

threadStatus :: MonadPrim RW m => ThreadId -> m ThreadStatus

threadCapability :: MonadPrim RW m => ThreadId -> m (Int, Bool)

threadIdToCInt :: ThreadId -> CInt

Something that is not available in base. Convert a ThreadId to a regular integral type.

Since: 0.0.0

id2TSO :: ThreadId -> ThreadId#
