<p>Get character data pointer for a string at <tt>index</tt> without
|
|
modifying or coercing the value. Returns a non-<tt>NULL</tt> pointer to
|
|
the read-only, NUL-terminated string data. Returns <tt>NULL</tt> if the
|
|
value is not a string or the index is invalid.</p>
|
|
|
|
<p>To get the string byte length explicitly (which is useful if the string
|
|
contains embedded NUL characters), use
|
|
<tt><a href="#duk_get_lstring">duk_get_lstring()</a></tt>.</p>

<div class="note">
|
|
A non-<tt>NULL</tt> return value is guaranteed even for zero length strings;
|
|
this differs from how buffer data pointers are handled (for technical reasons).
