[mpich-discuss] MPI i/o like fopen (filename, "rb")

[Muhammad Zulfikar Handana]

dear,
i have a little confused about MPI i/o, because iam new for this
programming. i have some question.
if i want make some program with this code

1)

int get_size(char *filename)
{
    struct stat buf;
    stat(filename,&buf);
    int j =buf.st_size;

    return j;
}

2)
 key = fopen(key_file, "rb");
        fread(Kunci, pk, 1, key);
        for(i=0;i<Nk*4;i++)
        Key[i]=Kunci[i];

3) hasil = fopen (file_akhir, "wb");
    for (k=0;k<(((block-1)*16)+pad);k++)
    {
               fputc(output[k], hasil);
        }
        fclose (hasil);

how to translate that code into MPI i / o ?
thanks a lot for your attention

Regards


Handana
