NAME
     MPI_Attr_delete - Deletes an attribute value associated with a key

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Attr_delete ( comm, keyval )
          MPI_Comm comm;
          int      keyval;


     C++:

          #include <mpi.h>

          void Comm::Delete_attr(
          int               comm_keyval)


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER comm, keyval, ierror

          CALL MPI_ATTR_DELETE(comm, keyval, ierror)


STANDARDS
     This release implements the MPI 1.2 standard, as documented by the MPI
     Forum in the spring 1997 release of MPI:  A Message Passing Interface
     Standard.

DESCRIPTION
     The MPI_Attr_delete routine deletes an attribute value associated with a
     key.  This routine accepts the following parameters:

     comm      Specifies the communicator to which the attribute is attached
               (handle)

     keyval    Specifies the key value of the deleted attribute (integer)

SEE ALSO
     MPI_Attr_get(3), MPI_Attr_put(3), MPI_Keyval_create(3)

     ierror
          Specifies the return code value for successful completion, which is
          in MPI_SUCCESS.  MPI_SUCCESS is defined in the mpif.h file.
