There may be a need to somehow "abort" the file so that it is as though you never started writing it. But it may be sufficient to do this if the process owning the fd exits without calling close().
I very much disagree with others that say POSIX should be followed. The suggested method of writing a file is what is wanted in probably 95% of the time that files are written. It should be the basic operation, while "dynamic other processes can see the blocks change as I write them" is an extremely rare operation that should be the one requiring complex hacks.
