no no please, i'm not asking for a change in sockaddr format. the former
discussion went really off-topic, and we discussed stuff that had not
much to do with the actual bug.
let me rephrase the problem. the following code:
#include <sys/socket.h>
#include <sys/un.h>
main ()
{
sockaddr_un test = { AF_LOCAL, "" };
}
which might be arguably nice or crap code, complies with the sockaddr_un
definition, but it will only compile on GNU/Linux. on GNU it fails
with:
$ g++ -c test.c -o /dev/null
test.c: In function `int main()':
test.c:6: invalid conversion from `const char*' to `unsigned char'
and the bug can be fixed without changing the definition, by just
applying this:
