One other minor related issue is that it no specifier at all is legal to use with unpacked arrays. That leaves users no choice but to manually iterated unpacked arrays and print each element.

They shall not be used with any unpacked aggregate type." "- %u and %z format specifiers - For packed data, %u and %z are defined to operate as though the operation were applied to the equivalent vector. - For unpacked struct data, %u and %z are defined to apply as though the operation were performed on each member in declaration order. - For unpacked union data, %u and %z are defined to apply as though the operation were performed on the first member in declaration order. - %u and %z are not defined on unpacked arrays." 1. There is an apparent contradiction, that the first part seems to say that %u and %z, among others, "shall not be used with any unpacked aggregate type", and the second part says that they can. 2. If %u and %z can be defined for unpacked structs and unions, why not %b, etc. ? Shalom Shalom Bresticker Intel Jerusalem LAD DA +972 2 589-6852 +972 54 721-1033 I don't represent Intel
