callback_info

Description

This interface can be implemented by any object that can issue callbacks. The get_callbacks method returns a attr_value_t list of type [[(o|n)sss*]] where o is the object that installed the callback (if applicable, otherwise NIL). The sss strings are:

• A one liner description about the callback. Could for example contain the interface method that installed the callback, if such one exist.
• The function name.
• A string describing the user data.

SIM_INTERFACE(callback_info) {
        attr_value_t (*get_callbacks)(conf_object_t *obj);
};
#define CALLBACK_INFO_INTERFACE "callback_info"

Execution Context

Cell Context for all methods, but must be called from a callback receiving a handle of type instruction_handle_t.
