Currently we have exception tree of classes inherited from OSError When we use C API we can call PyErr_SetFromErrno and PyErr_SetFromErrnoWithFilename[Object] functions. This ones raise concrete exception class (FileNotFoundError for example) looking on implicit errno value. I cannot see the way to do it from python.
Maybe adding builtin like exception_from_errno(errno, filename=None) make some value? Function returns exception instance, concrete class depends of errno value For example if I've got EPOLLERR from poller call I can get error code via s.getsockopt(SOL_SOCKET, SO_ERROR) but I cannot raise concrete exception from given errno code. -- Thanks, Andrew Svetlov _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
