MPI_Win_set_attr - Sets the value of a window attribute.
#include <mpi.h>
int MPI_Win_set_attr(MPI_Win win, int win_keyval, void *attribute_val)
INCLUDE ’mpif.h’

void MPI::Win::Set_attr(int win_keyval, const void* attribute_val)
- win
- Window to which attribute will be attached (handle).
- win_keyval
- Key value (integer).
- attribute_val
- Attribute
value.
- IERROR
- Fortran only: Error status (integer).
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.
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.
