MPI_Win_set_attr(3OpenMPI)MPI_Win_set_attr(3OpenMPI)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)
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
C++ Syntax
#include <mpi.h>
void MPI::Win::Set_attr(int win_keyval, const void* attribute_val)
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. C++ func-
tions 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.

Hi,
I am attempting to test the input value for an integer. And if the value is not an integer, the intent is to complain about it and exit. Only if I can get past the syntax error, life will be full.
