MPI_Type_delete_attr(3OpenMPI)                                                MPI_Type_delete_attr(3OpenMPI)



NAME
       MPI_Type_delete_attr - Deletes a datatype-caching attribute value associated with a key.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Type_delete_attr(MPI_Datatype type, int type_keyval)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_TYPE_DELETE_ATTR(TYPE, TYPE_KEYVAL, IERROR)
            INTEGER   TYPE, TYPE_KEYVAL, IERROR


C++ Syntax
       #include <mpi.h>
       void MPI::Datatype::Delete_attr(int type_keyval)


INPUT/OUTPUT PARAMETER
       type      Data type from which the attribute is deleted (handle).n


INPUT PARAMETER
       type_keyval
                 Key value (integer).


OUTPUT PARAMETER
       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_Type_delete_attr  deletes a datatype-caching attribute value associated with a key. This routines
       partially replaces MPI_Attr_delete, which is now deprecated.


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.
