18.2.407. MPI_Type_set_attr
MPI_Type_set_attr - Sets a key value/attribute pair to a data type.
18.2.407.1. SYNTAX
18.2.407.1.1. C Syntax
#include <mpi.h>
int MPI_Type_set_attr(MPI_Datatype type, int type_keyval,
void *attribute_val)
18.2.407.1.2. Fortran Syntax (see FORTRAN 77 NOTES)
USE MPI
! or the older form: 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
18.2.407.1.3. Fortran 2008 Syntax
USE mpi_f08
MPI_Type_set_attr(datatype, type_keyval, attribute_val, ierror)
TYPE(MPI_Datatype), INTENT(IN) :: datatype
INTEGER, INTENT(IN) :: type_keyval
INTEGER(KIND=MPI_ADDRESS_KIND), INTENT(IN) :: attribute_val
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
18.2.407.2. INPUT/OUTPUT PARAMETER
type
: Data type to which attribute will be attached (handle).
18.2.407.3. INPUT PARAMETERS
type_keyval
: Key value (integer).attribute_val
: Attribute value.
18.2.407.4. OUTPUT PARAMETER
IERROR
: Fortran only: Error status (integer).
18.2.407.5. DESCRIPTION
For the given data type, MPI_Type_set_attr sets the key value to the value of the specified attribute.
18.2.407.6. 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.
18.2.407.7. 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.
