pthread_create start routine without args

[discostu]

I have a hello world program of which I am trying to use pthreads. I don't know what to put for args since there aren't any. I've tried both NULL and (void*), and neither seem to work.

pthread_create(&worldthread, NULL, (int*)&world, (void*));

int world( void )
{
    printf( "world" );
    return( 0 );
}

Thanks in advance!
