MPI_Type_free_keyval(3OpenMPI)                                                MPI_Type_free_keyval(3OpenMPI)



NAME
       MPI_Type_free_keyval - Frees a previously created type key value.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Type_free_keyval(int *type_keyval)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_TYPE_FREE_KEYVAL(TYPE_KEYVAL, IERROR)
            INTEGER   TYPE_KEYVAL, IERROR


C++ Syntax
       #include <mpi.h>
       static void MPI::Datatype::Free_keyval(int& type_keyval)


INPUT/OUTPUT PARAMETER
       type_keyval
                 Key value to free (integer).


OUTPUT PARAMETER
       IERROR    Fortran only: Error status (integer).


DESCRIPTION
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.
