<p>Like <code><a href="#duk_eval">duk_eval()</a></code> but catches errors
|
|
related to compilation (such as syntax errors in the source). A zero return
|
|
value indicates success and the eval result is left on the stack top.
|
|
A non-zero return value indicates an error, and the error is left on the stack top.</p>
