Solution: remove duplicated and redundant code

Solution: explicitly compare result against 0

Solution: make const

Solution: harmonize

Solution: disable cppcoreguidelines-pro-type-static-cast-downcast warning

Solution: remove redundant else

Solution: add LIBZMQ_UNUSED

Solution: changed condition

Solution: remove redundant else

Solution: harmonize

Problem: numerous hicpp-signed-bitwise warnings that cannot easily be solved because of externally defined types

Solution: disable this warning for now

Solution: change to comply with naming conventions

Solution: mark parameter as unused depending on platform definitions

Solution: correct spelling

Solution: declare functions noexcept

Solution: add compile check

Solution: add dummy pointer meber to union instead

Solution: harmonize, remove redundant checks

Solution: introduced named constants

Problem: code style issues in options_t (C-style cast, suboptimal std::string::find call, redundant method is_valid)

Solution: resolved these issues

Solution: use strtol instead

Solution: make ip_address_mask_t independent of ip_address_t, they do not share that much, remove some code duplication between ip_address_t and ip_addr_t

Solution: declare private

Solution: encapsulate data member properly

Problem: temporary files in repo

Solution: remove them

Remove duplication between stream_t and router_t

Solution: pull up functionality to base class

Solution: pulled up to routing_socket_base_t

Solution: pull up into routing_socket_base_t

Solution: extract into common base class routing_socket_base_t, for now as protected

Solution: add an intermediary base class routing_socket_base_t, move common functionality there and make connect_routing_id private

Solution: make them private

More code style improvements

Solution: replace by reinterpret_casts or avoid entirely

Solution: use char* from the beginning

Solution: extracted constants

Solution: use UCHAR_MAX constant instead

Solution: calculate from field sizes

Solution: change return type to void, and remove redundant result checks
