SocketSetReuseAddr

Description

Allow a listening socket to reclaim a port still in TIME_WAIT. Maps to SO_REUSEADDR on POSIX and SO_EXCLUSIVEADDRUSE on Windows – Windows’s SO_REUSEADDR lets other processes hijack the port, which is the opposite of what callers want. The shim normalises both to “let me restart the server quickly without ADDRINUSE from TIME_WAIT” semantics.

Success

Returns true. The fd has the requested setting.

Failure

Returns false. The fd is unchanged; the failing syscall is logged.
