## Description

Once you read a prelude_msg_t object, you need to decode this message. In case this is an IDMEF style message, the following API allow to read the relevant IDMEF fields from the prelude_msg_t object, and create the IDMEF object from it's content.

The function you're most probably looking to use is `idmef_message_read()`, and here is an example on how to use it:

    int ret;
    prelude_msg_t *pmsg;
    idmef_message_t *message;

    pmsg = whatever_method_to_get_a_prelude_msg();

    ret = idmef_message_new(&message);
    if ( ret < 0 )
            return ret;

    ret = idmef_message_read(message, pmsg);

This will decode the full IDMEF message stored within pmsg into the idmef_message_t IDMEF object and it's childrens.
