Re: [Kamailio-Users] custom module depends on usrloc, the load order

Greetings,

I have 2 questions.

1. I've created custom module where I'd like to get number of users from

usrloc module. Here is the code:

LOG(L_INFO,"PRESOURCE: Initializing\n"); bind_usrloc = (bind_usrloc_t)find_export("ul_bind_usrloc", 1, 0); if ( !bind_usrloc ) { LOG(L_CRIT, "Can't bind usrloc (find_export) check if loaded"); goto error; } if ( !bind_usrloc(&ul) ) { LOG(L_CRIT, "Can't bind usrloc"); goto error; }

bind_usrloc() returns 0 on success, so the condition in the if is wrong. Actually the bind_usrloc() is successfully.

Cheers, Daniel

When this code is enabled if fails on second if. Looks like usrloc module is not loaded. Here's the log

In config script loadmodule("usrloc.so") is prior to load my custom module. When I disable above code, then load order follows config file order.

2. Here's how I wanted to get number of users:

unsigned long get_number_of_users() { return ul.get_number_of_users(); }

But usrloc_api_t does not contain this cmd function despite it's exported in usrloc module

typedef struct usrloc_api { int use_domain; int db_mode; unsigned int nat_flag;

    register_udomain_t   register_udomain;
    get_all_ucontacts_t  get_all_ucontacts;

    insert_urecord_t     insert_urecord;
    delete_urecord_t     delete_urecord;
    get_urecord_t        get_urecord;
    lock_udomain_t       lock_udomain;
    unlock_udomain_t     unlock_udomain;

    release_urecord_t    release_urecord;
    insert_ucontact_t    insert_ucontact;
    delete_ucontact_t    delete_ucontact;
    get_ucontact_t       get_ucontact;

    update_ucontact_t    update_ucontact;

    register_watcher_t   register_watcher;
    unregister_watcher_t unregister_watcher;
    register_ulcb_t      register_ulcb;

} usrloc_api_t;

Thanks, Toly
