NAME
MPI_Win_set_info - Set window info hints
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Win_set_info(MPI_Win win, MPI_Info info)
Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_WIN_SET_INFO(WIN, INFO, IERROR)
INTEGER WIN, INFO, IERROR
Fortran 2008 Syntax
USE mpi_f08
MPI_Win_set_info(win, info, ierror)
TYPE(MPI_Win), INTENT(IN) :: win
TYPE(MPI_Info), INTENT(IN) :: info
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
INPUT PARAMETERS
win Window on which to set info hints
info Info object containing hints to be set on win
OUTPUT PARAMETERS
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_WIN_SET_INFO sets new values for the hints of the window associated
with win. MPI_WIN_SET_INFO is a collective routine. The info object
may be different on each process, but any info entries that an imple-
mentation requires to be the same on all processes must appear with the
same value in each process's info object.
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.
