MPI_Lookup_name(3OpenMPI)                                                          MPI_Lookup_name(3OpenMPI)



NAME
       MPI_Lookup_name - Finds port associated with a service name


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Lookup_name(char *service_name, MPI_Info info,
            char *port_name)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_LOOKUP_NAME(SERVICE_NAME, INFO, PORT_NAME, IERROR)
            CHARACTER*(*)  SERVICE_NAME, PORT_NAME
            INTEGER        INFO, IERROR


C++ Syntax
       #include <mpi.h>
       void MPI::Lookup_name(const char *service_name, const MPI::Info& info,
            char* port_name)


INPUT PARAMETERS
       service_name  A service name (string).

       info          Options to the name service functions (handle). No options currently supported.


OUTPUT PARAMETERS
       port_name     a port name (string).

       IERROR        Fortran only: Error status (integer).


DESCRIPTION
       This function retrieves a port_name published under service_name by a previous invocation of MPI_Pub-lish_name. MPI_Publish_name.
       lish_name. The application must supply a port_name buffer large enough to hold the  largest  possible
       port name (i.e., MPI_MAX_PORT_NAME bytes).

       The info parameter should be MPI_INFO_NULL, as this routine does not parse any MPI Info arguments.


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++ 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.  Note  that MPI does not guarantee that an MPI program can continue past an
       error.

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