Macros to implement functions callable from javascript
As with all external functions, must be registered using JS::Object::registerFunction to make available to javascript. Function arguments should be validated, returning JS::Error object on failure.
#define	JS_DEFINE_FUNCTION(func, ...)
	Argument list is fixed. More...
#define	JS_DEFINE_FUNCTION_VAR(func)
	Arguments are passed as array. More...
#define	JS_DECLARE_FUNCTION(func)    jerry_value_t func(const jerry_call_info_t*, const jerry_value_t[], const jerry_length_t);
	Declare a function wrapper. More...

Functions
jerry_value_t	Jerryscript::create_arg_count_error (const char *functionName)
