Publishes that a range of memory is managed by a specific control block, so that base_control and cycle_member_ptr can use automatic deduction of ownership.

Member Function Documentation

lookup()

static auto cycle_ptr::detail::base_control::publisher::lookup ( void *  addr, std::size_t  len  ) -> intrusive_ptr< base_control >

static

Perform a lookup, to figure out which control manages the given address range.

Finds the base_control for which a publisher is active. The range is usually smaller than the range managed by the control.

Parameters

[in]	addr	Object offset for which to find a base_control.
[in]	len	Sizeof the object for which to find a base control.

Returns

Base control owning the argument address range.

Exceptions

std::runtime_error
