oops. I see ... need to test for empty string.
nothrow pure size_t strlen2(const(char)* c) {
if (c is null || *c==0)
return 0;
const(char)* c_save = c;
while (*c){ c+=4; }
while (*c==0){ c--; }
c++;
return c - c_save;
}
Why not just do
nothrow pure size_t strlen2(const(char)* c) {
if (!c)
return 0;
...
}
