NAME

       MPI_Free_mem    -   Frees   memory   that   has  been  allocated  using
       MPI_Alloc_mem.

SYNTAX


C Syntax

       #include <mpi.h>
       int MPI_Free_mem(void *base)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_FREE_MEM(BASE, IERROR)
            <type> BASE(*)
            INTEGER IERROR

C++ Syntax

       #include <mpi.h>
       void MPI::Free_mem(void *base)

INPUT PARAMETER

       base      Initial address of memory segment allocated by  MPI_Alloc_mem
                 (choice).

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_Free_mem frees memory that has been allocated by MPI_Alloc_mem.

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.
