Hello,

i m using mappi_create in my callpoint function and im adding a new elem in my list.
so i’m going in my callpoint function everytime im addind an elem in my list.
How to avoid recursive callpoint.

tailf:callpoint cause_callpoint_add {
tailf:transaction-hook node;
tailf:config “true”;
}

HI,
See maapi_attach(). I.e. you attach to the transaction in your init() callback:

static int init_trans(struct confd_trans_ctx *tctx)
{
    OK(maapi_attach(msock, my__ns, tctx));
    confd_trans_set_fd(tctx, workersock);
    return CONFD_OK;
}

Note that there is no need to commit, e.g. using maapi_apply_trans() after your maapi_create() since you attached to a transaction that will be committed after your hook.

@cohult it doesn’t works ;(
I’m reading the confd user guide but it’s not very clear.
workersock is the socket inside tctx (tctx->fd) right ?
so inside my function_create_elem at the begining i add init_trans right ?
Do you have an exemple ?

If you have access to ConfD premium, examples.confd/snmpa/11-different-keys/hook.c is a good reference, else something similar to one of the below:
