free package:base

Free a block of memory that was allocated with malloc, mallocBytes, realloc, reallocBytes, new or any of the newX functions in Foreign.Marshal.Array or Foreign.C.String.

Deallocate a memory pool and everything which has been allocated in the pool itself.

Release the storage associated with the given FunPtr, which must have been obtained from a wrapper stub. This should be called whenever the return value from a foreign import wrapper function is no longer required; otherwise, the storage it uses will leak.

Dissolve the association between the stable pointer and the Haskell value. Afterwards, if the stable pointer is passed to deRefStablePtr or freeStablePtr, the behaviour is undefined. However, the stable pointer may still be passed to castStablePtrToPtr, but the Ptr () value returned by castStablePtrToPtr, in this case, is undefined (in particular, it may be nullPtr). Nevertheless, the call to castStablePtrToPtr is guaranteed not to diverge.

Freeze a call-stack, preventing any further call-sites from being appended.

pushCallStack callSite (freezeCallStack callStack) = freezeCallStack callStack

Freeze the stack at the given CallStack, preventing any further call-sites from being pushed onto it.

A pointer to a foreign function equivalent to free, which may be used as a finalizer (cf ForeignPtr) for storage allocated with malloc, mallocBytes, realloc or reallocBytes.

Make a mutable array of arrays immutable, without copying.

Make a mutable byte array immutable, without copying.
