Description
JS_ValueToUint16 converts a specified JS value, v, to a JS double, and then to a 16-bit integer, if it fits. The fractional portion of the double is dropped silently during conversion to an integer value. If the double is out of range, JS_ValueToUint16 reports an error and conversion fails. The converted value is stored in the uint16 pointed to by ip.
You can convert a JS value to an integer if the JS value to convert is a JSVAL_INT, JSVAL_DOUBLE, or JSVAL_BOOLEAN. If the JS value is a JSVAL_STRING that contains numeric values and signs only, conversion also succeeds. If the JS value is a JSVAL_OBJECT, conversion is successful if the object supports its own conversion function.
If the conversion is successful, JS_ValueToInt32 returns JS_TRUE. Otherwise, it reports an error and returns JS_FALSE.
