MPI_Type_set_attr(3) Open MPI MPI_Type_set_attr(3)NAMEMPI_Type_set_attr - Sets a key value/attribute pair to a data type.
SYNTAXC Syntax
#include <mpi.h>
int MPI_Type_set_attr(MPI_Datatype type, int type_keyval,
void *attribute_val)
Fortran Syntax (see FORTRAN 77 NOTES)
INCLUDE 'mpif.h'
MPI_TYPE_SET_ATTR(TYPE, TYPE_KEYVAL, ATTRIBUTE_VAL, IERROR)
INTEGER TYPE, TYPE_KEYVAL, IERROR
INTEGER(KIND=MPI_ADDRESS_KIND) ATTRIBUTE_VAL
C++ Syntax
#include <mpi.h>
void MPI::Datatype::Set_attr(int type_keyval, const void* attribute_val)
INPUT/OUTPUT PARAMETER
type Data type to which attribute will be attached (handle).
INPUT PARAMETERS
type_keyval
Key value (integer).
attribute_val
Attribute value.
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
DESCRIPTION
For the given data type, MPI_Type_set_attr sets the key value to the
value of the specified attribute.
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.
