[Interest] Status: Incomplete

Nothing to do with Qt but given our previous given out previous conversation on how OpenSource bugs are left to rot then mass exterminated, this one just showed up in my inbox this morning. It's noteworthy because, yet again, to avoid working on something the maintainer flagged the report

. This deviates from standard C/C++ where you can. Before opening an output file you need to test for its existence then delete it. You can also play games with opening the file for I/O and truncating, but, success is file system dependent on that one. -- Roland Hughes, President Logikal Solutions (630)-205

Re: [Interest] QFile::write(const QByteArray&) does not, , write, all data?

read/write was not an error because they ran smack dab into the middle of the overlap. SOME I/O might have happened and that value had to be returned. ___Hopefully___ the developer can find the real error on their own. Qt is written in C++ so it can do better. -- Roland Hughes, President Logikal Solu
