  GType return_type

Description [src]

Create a function in context. If name is NULL an anonymous function will be created. When the function is called by JavaScript or jsc_value_function_call(), callback is called receiving an GPtrArray of JSCValues with the arguments and then user_data as last parameter. When the function is cleared in context, destroy_notify is called with user_data as parameter.

Note that the value returned by callback must be fully transferred. In case of boxed types, you could use G_TYPE_POINTER instead of the actual boxed GType to ensure that the instance owned by JSCClass is used. If you really want to return a new copy of the boxed type, use #JSC_TYPE_VALUE and return a JSCValue created with jsc_value_new_object() that receives the copy as instance parameter.


context JSCContext

A JSCContext.

 The data is owned by the caller of the function.
name const char*

The function name or NULL.

 The argument can be NULL.
 The data is owned by the caller of the function.
 The value is a NUL terminated UTF-8 string.
callback GCallback

A GCallback.

user_data gpointer

User data to pass to callback.

 The argument can be NULL.
 The data is owned by the caller of the function.
destroy_notify GDestroyNotify

Destroy notifier for user_data.

 The argument can be NULL.
return_type GType

The GType of the function return value, or G_TYPE_NONE if the function is void.

Return value

Returns: JSCValue

A JSCValue.

 The caller of the function takes ownership of the data, and is responsible for freeing it.
