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.
