First code I open:

Code:

void getword(char *p, long *l)
{
        char    *pp;
        pp = (char *) l;
        *pp++ = *p++;
        *pp++ = *p++;
        *pp++ = *p++;
        *pp++ = *p++;
}

void putword(char *p, long *l)
{
        char *pp;

        pp = (char *) l;
        *p++ = *pp++;
        *p++ = *pp++;
        *p++ = *pp++;
        *p++ = *pp++;
}

This will do different things on big-endian and little endian platforms
This assumes sizeof(long) == 4 bytes
