Als de file op dezelfde machine (of hetzelfde type van machine) geschreven
en gelezen wordt, zou dat geen enkel probleem mogen zijn.

struct st buf;

int *handle = open("filename", ...)

En dan :

read(handle, &buf, sizeof(buf));

of

write(handle,&buf, sizeof(buf));

Wel niet vergeten testen of the return waarde van read() en write() gelijk
is aan sizeof(buf)...
