Can any body tell me what is advantage of static thread function ?

[Qt embedded developer]

I want to know what is advantage of static thread function ?

static void * threadFunc(void *arg)
{
char *s = (char *) arg;
printf("%s", s);
return (void *) strlen(s);
}

int main(int argc, char *argv[])
{
pthread_t t1;
void *res;
int s;
s = pthread_create(&t1, NULL, threadFunc, "Hello world\n");
if (s != 0)
errExitEN(s, "pthread_create");
printf("Message from main()\n");
s = pthread_join(t1, &res);
if (s != 0)
errExitEN(s, "pthread_join");
printf("Thread returned %ld\n", (long) res);
exit(EXIT_SUCCESS);
}

@Qt-embedded-developer In this case static simply means the threadFunc is only accessible from this translation unit (see https://www.sandordargo.com/blog/2021/07/07/2-ways-to-use-static-with-functions-cpp). It has no real "advantages" here.
