Manipulation of Unix domain sockets
!MOD!)
The tt(zsh/net/socket) module makes available one builtin command:
startitem()
findex(zsocket)
cindex(sockets)
cindex(sockets, Unix domain)
item(tt(zsocket) [ tt(-altv) ] [ tt(-d) var(fd) ] [ var(args) ])(
tt(zsocket) is implemented as a builtin to allow full use of shell
command line editing, file I/O, and job control mechanisms.
)
enditem()
subsect(Outbound Connections)
cindex(sockets, outbound Unix domain)
startitem()
item(tt(zsocket) [ tt(-v) ] [ tt(-d) var(fd) ] var(filename))(
Open a new Unix domain connection to var(filename).
The shell parameter tt(REPLY) will be set to the file descriptor
associated with that connection. Currently, only stream connections
are supported.
If tt(-d) is specified, its argument
will be taken as the target file descriptor for the
connection.
In order to elicit more verbose output, use tt(-v).
File descriptors can be closed with normal shell syntax when no longer
needed, for example:
example(exec {REPLY}>&-)
)
enditem()
subsect(Inbound Connections)
cindex(sockets, inbound Unix domain)
startitem()
item(tt(zsocket) tt(-l) [ tt(-v) ] [ tt(-d) var(fd) ] var(filename))(
tt(zsocket -l) will open a socket listening on var(filename).
The shell parameter tt(REPLY) will be set to the file descriptor
associated with that listener.
If tt(-d) is specified, its argument
will be taken as the target file descriptor for
the connection.
In order to elicit more verbose output, use tt(-v).
)
item(tt(zsocket) tt(-a) [ tt(-tv) ] [ tt(-d) var(targetfd) ] var(listenfd))(
tt(zsocket -a) will accept an incoming connection
to the socket associated with var(listenfd).
The shell parameter tt(REPLY) will
be set to the file descriptor associated with
the inbound connection.
If tt(-d) is specified, its argument
will be taken as the target file descriptor for the
connection.
If tt(-t) is specified, tt(zsocket) will return
if no incoming connection is pending. Otherwise
it will wait for one.
In order to elicit more verbose output, use tt(-v).
)
