SubjectRe: bidirectional named pipe?


According to the Understanding the Linux Kernel book I
plowed through yesterday afternoon the EXT2 file system
has a defined file type "socket," distinct from fifo.

How does one set up a named socket in a file system? Is it
a legacy constant that has never been supported or what?
