NAME

mpd  

FILE

/Users/goodell/svn/mpich2-1.2.1p1-tmp/src/pm/mpd/mpd.py

DESCRIPTION

usage: mpd [--host=<host> --port=<portnum>] [--noconsole] [--trace] [--echo] [--daemon] [--bulletproof] --ncpus=<ncpus> [--ifhn=<interface-hostname>] [--listenport=<listenport>] [--pid=<pidfilename>] --tmpdir=<tmpdir>] [-zc] [--debug]

Some long parameter names may be abbreviated to their first letters by using only one hyphen and no equal sign: mpd -h donner -p 4268 -n is equivalent to mpd --host=magpie --port=4268 --noconsole

--host and --port must be specified together; they tell the new mpd where

to enter an existing ring;
if they are omitted, the new mpd forms a stand-alone ring that other mpds may enter later --noconsole is useful for running 2 mpds on the same machine; only one of them will accept mpd commands --trace yields lots of traces thru mpd routines; currently too verbose --debug turns on some debugging prints; currently not verbose enough --echo causes the mpd echo its listener port by which other mpds may connect --daemon causes mpd to run backgrounded, with no controlling tty --bulletproof says to turn bulletproofing on (experimental) --ncpus indicates how many cpus are on the local host; used for starting processes --ifhn specifies an alternate interface hostname for the host this mpd is running on; e.g. may be used to specify the alias for an interface other than default --listenport specifies a port for this mpd to listen on; by default it will acquire one from the system --conlistenport specifies a port for this mpd to listen on for console connections (only used when employing inet socket for console); by default it will acquire one from the system --pid=filename writes the mpd pid into the specified file, or --pid alone writes it into /var/run/mpd.pid --tmpdir=tmpdirname where mpd places temporary sockets, etc. -zc is a purely EXPERIMENTAL option right now used to investigate zeroconf networking; it can be used to allow mpds to discover each other locally using multicast DNS; its usage may change over time
Currently, -zc is specified like this:
-zc N
where N specifies a 'level' in a startup set of mpds.
The first mpd in a ring
must have 1 and it will establish a ring of one mpd.
Subsequent mpds can specify
-zc 2 and will hook into the ring via the one at level 1.
Except for level 1, new mpds enter the ring via an mpd at level-1.

A file named .mpd.conf file must be present in the user's home directory with read and write access only for the user, and must contain at least a line with MPD_SECRETWORD=<secretword>

To run mpd as root, install it while root and instead of a .mpd.conf file use mpd.conf (no leading dot) in the /etc directory.'

FUNCTIONS

ctime(...) ctime(seconds) -> string

Convert a time in seconds since the Epoch to a string in local time. This is equivalent to asctime(localtime(seconds)). When the time tuple is not present, current time as returned by localtime() is used.

dumps(...) dumps(obj, protocol=0) -- Return a string containing an object in pickle format.


See the Pickler docstring for the meaning of optional argument proto.

md5new = openssl_md5(...) Returns a md5 hash object; optionally initialized with a string

random(...) random() -> x in the interval [0, 1).

sigchld_handler(signum, frame)

sleep(...) sleep(seconds)

Delay execution for a given number of seconds.
The argument may be a floating point number for subsecond precision.
