MPI_Free_mem

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.
