SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Win_get_name(MPI_Win win, char *win_name, int *resultlen)

Fortran Syntax

       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_WIN_GET_NAME(WIN, WIN_NAME, RESULTLEN, IERROR)
            INTEGER WIN, RESULTLEN, IERROR
            CHARACTER*(*) WIN_NAME

Fortran 2008 Syntax

       USE mpi_f08
       MPI_Win_get_name(win, win_name, resultlen, ierror)
            TYPE(MPI_Win), INTENT(IN) :: win
            CHARACTER(LEN=MPI_MAX_OBJECT_NAME), INTENT(OUT) :: win_name
            INTEGER, INTENT(OUT) :: resultlen
            INTEGER, OPTIONAL, INTENT(OUT) :: ierror

C++ Syntax

       #include <mpi.h>
       void MPI::Win::Get_name(char* win_name, int& resultlen) const

INPUT PARAMETER

       win       Window whose name is to be returned (handle).

OUTPUT PARAMETERS

       win_name  the  name  previously  stored  on the window, or an empty string if no such name
                 exists (string).

       resultlen Length of returned name (integer).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

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.
