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++ 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.
