Frees memory that has been allocated using mpi_alloc_mem.
#include <mpi.h> int MPI_Free_mem(void *base)
INCLUDE 'mpif.h' MPI_FREE_MEM(BASE, IERROR) <type> BASE(*) INTEGER IERROR
#include <mpi.h> void MPI::Free_mem(void *base)
Initial address of memory segment allocated by MPI_Alloc_mem (choice).
Fortran only: Error status (integer).
MPI_Free_mem frees memory that has been allocated by MPI_Alloc_mem.
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.
