[OMPI users] MPI_Alloc_Mem Error

[Chevchenkovic Chevchenkovic]

Hi,
here is a sample code that I ran to allocate memory using MPI_Alloc_mem
call.
*************
#include "mpi.h"
#include <stdio.h>

int main( int argc, char *argv[] )
{
   int  err;
   int j, count = 100;
   char *ap;

   MPI_Init( &argc, &argv );
   MPI_Errhandler_set( MPI_COMM_WORLD, MPI_ERRORS_RETURN );

       err = MPI_Alloc_mem( count, MPI_INFO_NULL, &ap );
       if (err) {
           int errclass;
           printf("\n Inside error!");
           printf("allocation failed");
         }
       else {
           printf("\n I m here in else part");
           /* Access all of this memory */
           MPI_Free_mem( ap );
       }
   MPI_Finalize();
   return 0;
}
