Even this, however, may not be totally safe, because of the possibility that the LIVE555 libraries, and/or your own code, may call system library functions that themselves are not 'thread safe'.<br><div><br></div><div>The VLC developers have identified a handful of such system library functions that are currently used the LIVE555 library code, and I am currently going through the code to remove/replace them.</div><div><br></div><div>The first such library function is "inet_ntoa()" (which, in our code, we renamed "our_inet_ntoa()"). I have just released a new version (2011.11.26) of the "LIVE555 Streaming Media" code that removes calls to this function.</div><div><br></div><div>In its place is a new class "AddressString" - defined in "groupsock/include/NetAddress.hh". For example, now, in the code, instead of calling</div><div><div> our_inet_addr(addr)</div><div>we now call</div><div> AddressString(addr).val()</div></div><div><br></div><div>If your own code happens to use multiple threads, you may wish to consider replacing any calls to "inet_ntoa()" with this new mechanism.</div><div><br></div><div>(A note to the VLC developers: This new release removes the need for the first, and largest of your 'LIVE555 patches'. I hope to do the same for your other patches also.)</div><br><br><div apple-content-edited="true">
