- * PR_SET_NAME
- * Set the task (or thread) name for the thread whose ID is in required
- * arg2 (int), using the value in the location pointed to by required arg1
- * (char*). The name can be up to CONFIG_TASK_NAME_SIZE long (including
- * any null termination). The thread ID of 0 will set the name of the
- * calling thread. As an example:
- *
- * prctl(PR_SET_NAME, "MyName", 0);
- *
- * PR_GET_NAME
- * Return the task (or thread) name for the for the thread whose ID is
- * optional arg2 (int), in the buffer pointed to by optional arg1 (char *).
- * The buffer must be CONFIG_TASK_NAME_SIZE long (including any null
- * termination). As an example:
- *
- * char myname[CONFIG_TASK_NAME_SIZE];
- * prctl(PR_GET_NAME, myname, 0);
