rexec(3N)              UNIX System V(Internet Utilities)              rexec(3N)


NAME
      rexec - return stream to a remote command

SYNOPSIS
      int rexec(char **ahost, ushort inport, char *user, char *passwd,
          char *cmd, int *fd2p);

DESCRIPTION
      rexec looks up the host ahost using gethostbyname [see gethostent(3N)],
      returning -1 if the host does not exist.  Otherwise ahost is set to the
      standard name of the host.  If a username and password are both
      specified, then these are used to authenticate to the foreign host;
      otherwise, the user's .netrc file in his or her home directory is
      searched for appropriate information.  If this fails, the user is
      prompted for the information.

      The port inport specifies which well-known DARPA 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 SOCKSTREAM is returned to the
      caller, and given to the remote command as its standard input and
      standard output.  If fd2p is non-zero, then a auxiliary channel to a
      control process will be setup, 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.

NOTES
      There is no way to specify options to the socket call that rexec makes.
