示例1: max
int
split (vec<str> *out, rxx pat, str expr, size_t lim, bool emptylast)
{
const char *p = expr;
const char *const e = p + expr.len ();
size_t n;
if (out)
out->clear ();
// check p < e to see that we're not dealing with an empty
// string (especially since x? matches "").
for (n = 0; p < e && n + 1 < lim; n++) {
