[Uimonen, Jaska] Ok will remove from this patch.
*size += wdata[i].pdata->size;We appear to be requiring that the size passed in is zero initialized which is a bit unusual and seems likely to break even if it happens to work right now.
[Uimonen, Jaska] Same comments I got from Pierre, obviously I'm not very good listener. Will initialize size to 0. --------------------------------------------------------------------- Intel Finland Oy Registered Address: PL 281, 00181 Helsinki Business Identity Code: 0357606 - 4 Domiciled in Helsinki
