It's documented: "namelen indicates the amount of space pointed to by name, in bytes." So, yes, for AF_UNIX sockets it is sizeof(struct sockaddr_un). > getsockname is underspecified in Posix Unix domain sockets, the other > address families use fixed size structs. > > FreeBSD's man page even says it is unsupported for Unix domain > sockets.
