17.2.160. MPI_Free_mem

MPI_Free_mem - Frees memory that has been allocated using MPI_Alloc_mem.

17.2.160.1. Syntax

17.2.160.1.1. C Syntax

#include <mpi.h>

int MPI_Free_mem(void *base)

17.2.160.1.2. Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'

MPI_FREE_MEM(BASE, IERROR)
    <type> BASE(*)
    INTEGER IERROR

17.2.160.1.3. Fortran 2008 Syntax

USE mpi_f08

MPI_Free_mem(base, ierror)
    TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: base
    INTEGER, OPTIONAL, INTENT(OUT) :: ierror

17.2.160.2. Input Parameter

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

17.2.160.3. Output Parameter

  • IERROR : Fortran only: Error status (integer).

17.2.160.4. Description

MPI_Free_mem frees memory that has been allocated by MPI_Alloc_mem.

17.2.160.5. Errors

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.

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.
