Maximum length of the path to a UNIX domain socket, sockaddr_un::sun_path member. POSIX requires that all systems support at least 100 bytes here, including the nul termination.

Reads a single byte which must be nul (an error occurs otherwise), and reads unix credentials if available. Fills in pid/uid/gid with -1 if no credentials are available. Return value indicates whether a byte was read, not whether we got valid credentials. On some systems, such as Linux, reading/writing the byte isn't actually required, but we do it anyway just to avoid multiple codepaths. Fails if no byte is available, so you must select() first. The point of the byte is that on some systems we have to use sendmsg()/recvmsg() to transmit credentials.
