 MPI_Win_set_attr 3 "#OMPI_DATE#" "#PACKAGE_VERSION#" "#PACKAGE_NAME#"
 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




 C++ Syntax
#include <mpi.h>
void MPI::Win::Set_attr(int win_keyval, const void* attribute_val)




 INPUT/OUTPUT PARAMETER
 1i
win
Window to which attribute will be attached (handle).


 INPUT PARAMETERS
 1i
win_keyval
Key value (integer).

 1i
attribute_val
Attribute value.


 OUTPUT PARAMETER
 1i
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. 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.
