|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).|
Intracommunicator over which call is collective (handle).
newcomm Intercommunicator with client as remote group (handle) IERROR Fortran only: Error status (integer).
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.
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions 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.
