I now saw Garret Wollman's function.
I like the use of the static-vars.
The use of sigemptyset makes it more transparenter for later changes,
that I hope won't occur, but at the moment it doesn't matter since
sigemptyset is
int
sigemptyset(set)
sigset_t *set;
{
int i;
for (i = 0; i < _SIG_WORDS; i++)
set->__bits[i] = 0;
return (0);
}
I attached a patch against patch-lo anyways (sorry ;-)
