MPI_Comm_delete_attr(3)

NAME
     MPI_Comm_delete_attr - Deletes a communicator attribute value associated
     with a key

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Comm_delete_attr ( comm, comm_keyval )
          MPI_Comm comm;
          int      comm_keyval;


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER comm, comm_keyval, ierror

          CALL MPI_COMM_DELETE_ATTR(comm, comm_keyval, ierror)


STANDARDS
     This function is defined in the MPI-2 standard.

     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_Comm_delete_attr routine deletes a communicator attribute value
     associated with a key.  This routine replaces MPI_Attr_delete which has
     been deprecated. This routine accepts the following parameters:

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

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

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