NAME
MPI_Free_mem - Frees memory that has been allocated using MPI_Al-
loc_mem.
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Free_mem(void *base)
Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_FREE_MEM(BASE, IERROR)
<type> BASE(*)
INTEGER IERROR
Fortran 2008 Syntax
USE mpi_f08
MPI_Free_mem(base, ierror)
TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: base
INTEGER, OPTIONAL, INTENT(OUT) :: 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.
