When you create code which can cause such situation, f.e.:
static s_mtx1, s_mtx2
init proc initmtx
s_mtx1 := hb_mutexCreate()
s_mtx2 := hb_mutexCreate()
Got it, thanks.
One more question,
under what circumstances deadlocks may occur?

It waits but can be interrupted, f.e.
Przemek
Here is a curosity:
if ( hb_threadMutexLock( s_pMtx ) )
{
...
...
hb_threadMutexUnlock( s_pMtx );
}
Does this function waits for the lock until
obtained or returns immediately?
If it waits until lock is obtained, then why we should
use 'if' statement?
