Class EWG_MANAGED_POINTER

-- Create a new pointer wrapper to a new memory area where
-- all bytes have been reset to zero.
-- Allocates as a_capacity bytes of new memory.
-- 'unshared' means if the Current object
-- gets collected by the garbage collector,
-- the allocated memory will
-- be freed as well.

-- 'shared' means if the Current object

-- Create a new pointer wrapper to a new memory area. Bytes
-- have a random value.

-- 'shared' means if the Current object

-- the allocated memory will
-- not be freed as well.

-- Create a new pointer wrapper to an existing memory area.
-- a_item must be the pointer to the memory area to wrap.
-- a_capacity specifies how big the memory area is that
-- the pointer points to.
-- 'unshared' means if the Current object
-- gets collected by the garbage collector,
-- the allocated memory will
-- be freed as well.

-- a_capacity specifies how big the memory area is that

-- 'shared' means if the Current object
-- gets collected by the garbage collector,
-- the memory allocated for the struct will
-- not be freed as well.

-- Create a pointer wrapper for the default pointer (NULL).

-- Size of the memory area that the wrapped
-- pointer points to.

-- Does item point to a valid C memory area ?

-- Is the contents of item referenced by other C or Eiffel code?
-- If is_shared is True then when the current object will be
-- collected by the garbage collector, the wrapped memory area will
-- also be freed.
-- This is a good idea, only if you can be sure that when the
-- Eiffel object gets collected, the C side does not have a reference
-- to the wrapped memory anymore.

-- Wrapped C pointer

-- Get the pointer at the a_pos-th
