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++ 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.
