Synopsis

newtype ConstPtr a = ConstPtr {
- unConstPtr :: Ptr a
}

Documentation

newtype ConstPtr a #

A pointer with the C const qualifier. For instance, an argument of type ConstPtr CInt would be marshalled as const int*.

While const-ness generally does not matter for ccall imports (since const and non-const pointers typically have equivalent calling conventions), it does matter for capi imports. See GHC #22043.

Since: base-4.18.0.0
