libsa provides cross-platform socket address bindings in C11, designed to be very portable and easy to use. This allows higher-level network code to use a single format but still communicate effectively with low-level native platform code.
StirlingLabs.sockaddr.Net provides all of libsa's functionality within .Net, avoiding additional memory allocations wherever possible. It provides an opaque sockaddr* type that is purely pointers or off-gc-heap refs, such that it can be simply cast to/from any other opaque sockaddr* type.
So addresses from any application or API that uses native bindings can be simply cast to StirlingLabs.sockaddr* and then can be manipulated and read without concern for the underlying platform format, then can simply be cast back when being passed back to the application API.
sockaddr isn't going to change once it exists on a platform, so it makes sense to just make a dedicated binding and interop library that can be used anywhere.
Configure GitHub Packages, then you can just:
dotnet add PROJECT package StirlingLabs.sockaddr.Netor just use NuGet however you would normally.
Development of this project is supported by Stirling Labs.
