 ~~~~~~~~~~~~~~~~~~
 
 It is possible to create Control Threads using the public API
-``rte_ctrl_thread_create()``.
+``rte_thread_create_control()``.
 Those threads can be used for management/infrastructure tasks and are used
 internally by DPDK for multi process support and interrupt handling.

-
 * eal: ``RTE_CPUFLAG_NUMFLAGS`` will be removed in DPDK 23.11 release.
   This is to allow new CPU features to be added without ABI breakage.
