3 years ago Please test the attached library version and see if it works any better for you. There have been a ton of recent changes that have not made it into an actual release yet. Thanks! (Note, this test version does not yet work on Windows.)

The reason the native library exceptions are not bubbled up to the Java level was because this library supports so many different types of native systems with different types/granularity of error reporting that it was nearly impossible to combine all of that into something consistent in Java-land. With the library version I attached (and in future releases), I have added two functions which should allow you to view both the native errno and the source code line that threw it. These method signatures are:
int getLastErrorCode();
int getLastErrorLocation();
If you test these out, you should be able to do a search through the source code files under src/main/c/Posix to determine which line threw the error and look up what the error code means for your OS. Thanks!
I have the problem the openPort() method returns "false" and I want to know the reason. I do not find a hint in the documentation from where I have to read this information.
Normally java libs put all such information in exceptions instead of returning just true/false. But this lib seems not to use exceptions much often in the manner java suggests. Do I miss something in the documentation?
