As the alignment of 64bit platforms may be defferent from 32bit one,
should it be like the following?
static inline char *
iwe_stream_add_point(char * stream, /* Stream of events */
char * ends, /* End of stream */
struct iw_event *iwe, /* Payload length + flags */
char * extra, /* More payload */
struct iw_request_info *info)
{
int event_len = IW_EV_POINT_LEN + iwe->u.data.length;
int point_len = IW_EV_POINT_LEN;
int lcp_len = IW_EV_LCP_LEN;
#ifdef CONFIG_COMPAT
if (info->flags & IW_REQUEST_FLAG_COMPAT) {
event_len = IW_EV_COMPAT_POINT_LEN + iwe->u.data.length;
point_len = IW_EV_COMPAT_POINT_LEN;
lcp_len = IW_EV_COMPAT_LCP_LEN;
}
#endif
/* Check if it's possible */
if(likely((stream + event_len) < ends)) {
iwe->len = event_len;
memcpy(stream, (char *) iwe, IW_EV_LCP_PK_LEN);
memcpy(stream + lcp_len,
((char *) iwe) + IW_EV_LCP_LEN + IW_EV_POINT_OFF,
IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN);
memcpy(stream + point_len, extra, iwe->u.data.length);
stream += event_len;
}
return stream;
}
(Note that IW_EV_COMPAT_LCP_LEN is just a example; not defined anywhere)
