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

       INCLUDE 'mpif.h'
       MPI_WIN_GET_INFO(WIN, INFO_USED, IERROR)
            INTEGER   COMM, INFO_USED, 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.
