Cross-platform library to retrieve network sockets information. Aims to be optimal by using low-level OS APIs instead of command line utilities. Provides unified interface and returns data structures which may have additional fields depending on platform.

Ok(())
}- On Windows, this library library uses GetExtendedTcpTable & GetExtendedUdpTable (iphlpapi), with an option to use the older GetTcpTable & GeUdpTable.
- On Linux and Android, it uses NETLINK_INET_DIAG protocol and performs pid lookup by traversing
procfs. - On macOS and iOS, it uses proc_pidfdinfo.
