Function JSObjectMakeFunctionWithCallback 

pub unsafe extern "C-unwind" fn JSObjectMakeFunctionWithCallback(
    ctx: JSContextRef,
    name: JSStringRef,
    call_as_function: JSObjectCallAsFunctionCallback,
) -> JSObjectRef

Available on crate features JSBase and JSObjectRef only.

Convenience method for creating a JavaScript function with a given callback as its implementation.

Parameter ctx: The execution context to use.

Parameter name: A JSString containing the function’s name. This will be used when converting the function to string. Pass NULL to create an anonymous function.

Parameter callAsFunction: The JSObjectCallAsFunctionCallback to invoke when the function is called.

Returns: A JSObject that is a function. The object’s prototype will be the default function prototype.

Safety

• ctx must be a valid pointer.
• name must be a valid pointer.
• call_as_function must be implemented correctly.
