interprocess communication.  They are similar to Internet sockets (and
utilize the same system calls) but instead of relying on IP addresses
and port numbers, UNIX-domain sockets have addresses in the local file
system address space.

When a UNIX-domain socket is attached to a location using the bind(2)
system call, the length of the provided path is not validated.  Later,
when this address was returned via other system calls, it is copied into
a fixed-length buffer.");
