int duk_is_strict_call(duk_context *ctx);

=summary
<p>Check whether the current (Duktape/C) function call is strict or not.
Returns 1 if the current function call is strict, 0 otherwise.  If the
call stack is empty, i.e. there is no active function call, returns 0.</p>

<div class="note">
All Duktape/C functions are currently strict, so at the monent this function
always returns 1 when called from inside a Duktape/C function call, and 0 when
called outside of a Duktape/C call (for a context with an empty call stack).
</div>

=example
if (duk_is_strict_call(ctx)) {
    printf("strict call\n");
} else {
    printf("non-strict call\n");
}
