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.

NAME

       MPI_Type_delete_attr -  Deletes an attribute value associated with a key on  a datatype

SYNOPSIS

       int MPI_Type_delete_attr(MPI_Datatype type, int type_keyval)

INPUT PARAMETERS

       type   - MPI datatype to which attribute is attached (handle)
       type_keyval
	      - The key value of the deleted attribute (integer)

THREAD AND INTERRUPT SAFETY

       This  routine  is  thread-safe.	This means that this routine may be safely used by multiple threads without the need for any user-provided
       thread locks.  However, the routine is not interrupt safe.  Typically, this is due to the use of memory allocation routines such as  malloc
       or other non-MPICH runtime routines that are themselves not interrupt-safe.

NOTES FOR FORTRAN

       All  MPI  routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list.  ierr
       is an integer and has the same meaning as the return value of the routine in C.	In Fortran, MPI routines are subroutines, and are  invoked
       with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All  MPI  routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran routines in
       the last argument.  Before the value is returned, the current MPI error handler is called.  By default, this error handler aborts  the  MPI
       job.   The  error  handler  may	be  changed  with  MPI_Comm_set_errhandler  (for  communicators), MPI_File_set_errhandler (for files), and
       MPI_Win_set_errhandler (for RMA windows).  The MPI-1 routine MPI_Errhandler_set may be used but its  use  is  deprecated.   The	predefined
       error handler MPI_ERRORS_RETURN may be used to cause error values to be returned.  Note that MPI does not guarentee that an MPI program can
       continue past an error; however, MPI implementations will attempt to continue whenever possible.

       MPI_SUCCESS
	      - No error; MPI routine completed successfully.
       MPI_ERR_OTHER
	      - Other error; use MPI_Error_string to get more information about this error code.
       MPI_ERR_KEYVAL
	      - Invalid keyval
