NAME
       libnvmf_connect_args_emit - render a connection as "nvme connect"
       options.

SYNOPSIS
       int libnvmf_connect_args_emit (const struct libnvmf_tid *tid , const
       struct libnvmf_params *params , void (*callback)(const char *arg, void
       *user_data) , void *user_data );

ARGUMENTS
       tid         addressing + identity, or NULL to emit the parameters only

       params      connection parameters, or NULL to emit the TID only

       callback    called once per formatted option, e.g. "--transport=tcp";
                   the string is only valid for the duration of the call

       user_data   caller context passed to callback

DESCRIPTION
       Emits the TID's set fields first, in fixed order (--transport,
       --traddr, --trsvcid, --nqn, --host-traddr, --host-iface, --hostnqn,
       --hostid), then the parameters in their iteration order.  Unset and
       reset parameters are skipped so the kernel default applies; a boolean
       parameter is emitted as a bare "--flag" when true and skipped when
       false.  Consumer-private options are the caller's to append.

       This is the consumption path for the resolved configuration: each
       connection becomes the option list of one "nvme connect" invocation.
       It also renders a connection as a human-readable, copy-pasteable
       command line for "config show" style output.

RETURN
       0 on success, -EINVAL when callback is NULL, -ENOMEM when formatting an
       option fails (the emission stops there).
