NAME
       MPI_Comm_accept	- Establishes communication with a client.

SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Comm_accept(char *port_name, MPI_Info info, int root, MPI_Comm comm, MPI_Comm *newcomm)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_COMM_ACCEPT(PORT_NAME, INFO, ROOT, COMM, NEWCOMM, IERROR)
	    CHARACTER*(*)  PORT_NAME
	    INTEGER	   INFO, ROOT, COMM, NEWCOMM, IERROR

C++ Syntax
       #include <mpi.h>
       MPI::Intercomm MPI::Intracomm::Accept(const char* port_name,
	    const MPI::Info& info, int root) const

INPUT PARAMETERS
       port_name Port name (string, used only on root).

       info	 Options given by root for the accept (handle, used only on root). No options currently supported.

       root	 Rank in comm of root node (integer).

       comm	 Intracommunicator over which call is collective (handle).

OUTPUT PARAMETERS
       newcomm	 Intercommunicator with client as remote group (handle)

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION
       MPI_Comm_accept	establishes  communication  with a client. It is collective over the calling communicator. It returns an intercommunicator
       that allows communication with the client, after the client has connected with the  MPI_Comm_accept  function  using  the  MPI_Comm_connect
       function.

       The port_name must have been established through a call to MPI_Open_port on the root.

ERRORS
       Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception  mechanism
       will be used to throw an MPI:Exception object.

       Before  the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for
       I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN  may	be
       used to cause error values to be returned.

       See the MPI man page for a full list of MPI error codes.
