[zeromq-dev] IPC address validity

[Stephen Lord]

In an ipc address the ipc:// defines the address type,
and the remainder defines the path to the socket. So you are defining
a file system path on your system.

ipc://test

would be test in the current working directory, all processes need to
run in the same directory.

ipc:///test

would be /test in the root of the filesystem, you probably need to be
root to create this.

ipc:///test/socket

Would be socket in the /test directory. ZMQ will not create the directory
for you so it will fail if it is not present, it will only create the socket 
named pipe itself.

Regular permission checks also apply, so applications need permission
to access the directory component of the socket path.

Read the man page here:
