NAME

       MPI_Win_get_info - Retrieves active window info hints

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Win_get_info(MPI_Win win, MPI_Info *info_used)

Fortran Syntax

       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_WIN_GET_INFO(WIN, INFO_USED, IERROR)
            INTEGER   COMM, INFO_USED, IERROR

Fortran 2008 Syntax

       USE mpi_f08
       MPI_Win_get_info(win, info_used, ierror)
            TYPE(MPI_Win), INTENT(IN) :: win
            TYPE(MPI_Info), INTENT(OUT) :: info_used
            INTEGER, OPTIONAL, INTENT(OUT) :: ierror

INPUT PARAMETERS

       win       Window from which to receive active info hints

OUTPUT PARAMETERS

       info_used New info object returned with all active hints on this window.

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_Win_get_info  returns  a new info object containing the hints of the window associated with win.  The
       current setting of all hints actually used by the system related to this window is returned in info_used.
       If no such hints exist, a handle to a newly created info object is returned that  contains  no  key/value
       pair. The user is responsible for freeing info_used via MPI_Info_free.

ERRORS

       Almost  all  MPI  routines  return  an  error  value; C routines as the value of the function and Fortran
       routines in the last argument.

       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.
