[ ... ] -> [ ... str! ]
=summary
<p>Push a string of explicit length to the stack. The string may contain
arbitrary data, including internal NUL characters. A pointer to the interned
string data is returned. If the operation fails, throws an error.</p>
<p>If <code>str</code> is <code>NULL</code>, an empty string is pushed to the stack
(regardless of what <code>len</code> is) and a non-<code>NULL</code> pointer to an
empty string is returned. The returned pointer can be dereferenced and
a NUL terminator character is guaranteed. This behavior differs from
<code><a href="#duk_push_string">duk_push_string</a></code> on purpose.</p>
<p>C code should normally only push valid CESU-8 strings to the stack.</p>
=example
const char tmp1[5] = { 'f', '\0', '\0', 'x', 'y' };
const char tmp2[1] = { '\0' };
duk_push_lstring(ctx, tmp1, 5); /* push the string "f\x00\x00xy" */
duk_push_lstring(ctx, tmp2, 1); /* push the string "\x00" */
duk_push_lstring(ctx, tmp2, 0); /* push empty string */
duk_push_lstring(ctx, NULL, 0); /* push empty string */
duk_push_lstring(ctx, NULL, 10); /* push empty string */
