Killing a thread having a listener socket
Hi All

I have a separate thread ListenerThread having a socket listening to info broadcasted by some remote server. This is created in my main thread.

Because of requirements, once the separate thread is started I need to avoid any blocking function on the main thread. Once it comes to the point to exit the application I cannot perform a join on the listener thread so the only thing I can do is to KILL it.

My questions are:

what happens to the network resoruces allocated by the function passed to the thead? Is the socket closed properly or there might be something pending? ( most worried about this )

is this procedure fast enough i.e. is the thread killed so that interrupt immediately ?

I am working with Linux ...what command or what can I check to ensure that there is no networking resource left pending or that something went wrong for the Operating system? whatever might be pending...

I am a bit scared that the killing of the application is not fast enough to guarantee that the exit of the application is clear.

I thank you very much for your help

Regards MNSTN

NOTE: I am using boost::thread in C++

pthread_getsequence_np

pthread_getsequence_np(3)				     Library Functions Manual					 pthread_getsequence_np(3)

NAME

       pthread_getsequence_np - Obtains the unique identifier for the specified thread.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       unsigned long   pthread_getsequence_np(
				     pthread_t	  thread);

STANDARDS

       None

PARAMETERS

       Thread object whose sequence number is to be obtained.

DESCRIPTION

       This  routine  obtains  and  returns  the DECthreads thread sequence number for the thread identified by the thread object specified in the
       thread argument.

       The thread sequence number provides a unique identifier for each existing thread.  A thread's thread sequence number is never reused  while
       the thread exists, but can be reused after the thread terminates.  The debugger interfaces use this sequence number to identify each thread
       in commands and in display output.

       The result of calling this routine is undefined if the thread argument does not specify a valid thread object.

RETURN VALUES

       No errors are returned.	This routine returns the DECthreads thread sequence number for the thread identified by the thread  object  speci-
       fied in the thread argument. The result of calling this routine is undefined if the thread argument does not specify a valid thread.

ERRORS

       None
