(If you have not written your own subclass of the "TaskScheduler"
class, then you can ignore this message.)
I have installed a new version (2010.05.27) of the "LIVE555 Streaming
Media" code that changes the "TaskScheduler" API to add new virtual
functions "turnOnBackgroundWriteHandling()" and
"turnOffBackgroundWriteHandling()" - similar to the existing "Read"
functions. These functions are used to test a socket for
writability, which is needed to implement asynchronous RTSP 'connect'
operations in the new, non-blocking version of the "RTSPClient"
interface - which I'll be releasing within a few days.
Implementations of these two new virtual functions have been added
for "BasicTaskScheduler" - the "TaskScheduler" implementation that we
supply in the released code. However, if you have implemented your
own subclass of "TaskScheduler", then you will need to write your own
implementation of the new virtual functions
"turnOnBackgroundWriteHandling()" and
"turnOffBackgroundWriteHandling()".
I have also made a small change to the signature of the
"UsageEnvironment::setResultErrMsg() virtual function, so if you have
your own subclass of "UsageEnvironment", you will need to modify your
implementation of "setResultErrMsg()" accordingly. This function now
takes a second, optional "err" parameter. If non-zero, this error
code is used - instead of 'errno' - to determine the error message
that's used.
