Hi Thomas,
  Thanks for the details. I never knew about "sctp_extendedEventLoop(lock

,unlock,mutex);". I will follow you advice.
  Regards,
Julio

Yes, make sure that every sctplib function is called exclusively.

For the event loop, the following das to be done: define functions to obtain
and release the mutex and give a pointer to the mutex as third argument:

void lock(void* mutexPtr)
{
   mutex = (YourMutexPtrType*)mutexPtr;
   Lock it ...
}

void unlock(void* mutexPtr)
{
   mutex = (YourMutexPtrType*)mutexPtr;
   Unlock it ...
}

sctp_extendedEventLoop(lock,unlock,mutex);


Also have a look into the file sctpsocketmaster.cc of the socket API. It
implements the thread-safe event loop for the socket API library.


Best regards
