#initialize(ptr, finalize = true) ⇒ Zproc

Attaches the pointer ptr to this instance and defines a finalizer for it if necessary.

Parameters:

  • ptr (::FFI::Pointer)
  • finalize (Boolean) (defaults to: true)

end

.new ⇒ CZMQ::Zproc

Create a new zproc. NOTE: On Windows and with libzmq3 and libzmq2 this function returns NULL. Code needs to be ported there.

#__ptr_give_ref ⇒ ::FFI::MemoryPointer

Note:

This detaches the current instance from the native object and thus makes it unusable.

Nullify internal pointer and return pointer pointer.

Returns:

  • (::FFI::MemoryPointer) —

    the pointer pointing to a pointer pointing to the native object

  ptr_ptr
end

#__undef_finalizer ⇒ void

Note:

Only use this if you need to and can guarantee that the native object will be freed by other means.

This method returns an undefined value.

Undefines the finalizer for this object.
