return stream to a remote command
cc [options] file -lsocket -lnsl
int rexec(char **ahost, int inport, char *user, char *passwd,
char *cmd, int *fd2p);
rexec looks up the host ahost
returning -1 if the host does not exist.
Otherwise, ahost is set to the standard name of the host.
The parameters are:
If a username and password are both specified, then these
are used to authenticate to the foreign host; otherwise,
the .netrc file in the user's home directory is
searched for appropriate information.
If this fails, the user is prompted for the information.
points to the pointer for the host
well-known port used for this connection;
this must be in network byte order
points to the user name
points to the password for the specified user name
points to the command to be executed
points to the descriptor for the control process
The port inport specifies which well-known
Internet port to use for the connection.
The protocol for connection is described in detail in rexecd.
If the call succeeds, a socket of type SOCK_STREAM
is returned to the caller, and given to
the remote command as its standard input and standard output.
is non-zero, then an auxiliary channel to a control
process will be set up, and a descriptor for it
will be placed in fd2p.
The control process will return diagnostic
output from the command (unit 2) on this channel,
and will also accept bytes on this channel as
signal numbers, to be forwarded to the process group of the command.
If fd2p is 0, then the standard error
(unit 2 of the remote command) will be made the same as its standard output
and no provision is made for sending arbitrary
signals to the remote process, although you may be
able to get its attention by using out-of-band data.
There is no way to specify options to the socket
call that rexec makes.
