Name

MPI_Win_set_attr - Sets the value of a window attribute.

Syntax

C Syntax


#include <mpi.h>
int MPI_Win_set_attr(MPI_Win win, int win_keyval, void *attribute_val)

Fortran Syntax (see FORTRAN 77 NOTES)


USE MPI
! or the older form: INCLUDE ’mpif.h’
MPI_WIN_SET_ATTR(WIN, WIN_KEYVAL, ATTRIBUTE_VAL, IERROR)
    INTEGER WIN, WIN_KEYVAL, IERROR
    INTEGER(KIND=MPI_ADDRESS_KIND) ATTRIBUTE_VAL

Fortran 2008 Syntax


USE mpi_f08
MPI_Win_set_attr(win, win_keyval, attribute_val, ierror)
    TYPE(MPI_Win), INTENT(IN) :: win
    INTEGER, INTENT(IN) :: win_keyval
    INTEGER(KIND=MPI_ADDRESS_KIND), INTENT(IN) :: attribute_val
    INTEGER, OPTIONAL, INTENT(OUT) :: ierror

Input/Output Parameter

win
Window to which attribute will be attached (handle).

Input Parameters

win_keyval
Key value (integer).
attribute_val
Attribute value.

Output Parameter

IERROR
Fortran only: Error status (integer).

Description

Fortran 77 Notes

The MPI standard prescribes portable Fortran syntax for the ATTRIBUTE_VAL argument only for Fortran 90. FORTRAN 77 users may use the non-portable syntax


     INTEGER*MPI_ADDRESS_KIND ATTRIBUTE_VAL

where MPI_ADDRESS_KIND is a constant defined in mpif.h and gives the length of the declared integer in bytes.

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.
