Hi there,

I think the DPDK uses the pthread_ functions to manages its threads. You can see in `rte_eal_init` in `lib/librte_eal/linux/eal.c` that it "spawns" the threads using

```
/* create a thread for each lcore */
ret = pthread_create(&lcore_config[i].thread_id, NULL,
eal_thread_loop, NULL);
```

So I think you should be able to use other pthread_ functions without problems from inside the EAL threads.

Hope that helps.

Regards,

Pavel.

I need to emulate the pthread_setspecific and pthread_getspecific for EAL threads. I don’t find any suitable APIs in the DPDK to access the TLS and get and set keys.

I launched a number of threads using the rte_eal_remote launch but I don’t find any API that allows me to access the TLS for those threads.
