Using the standard Win32 file I/O API's (CreateFile/ReadFile/etc), I'm trying to wait for a file to become readable, or for an exception to occur on the file. If Windows had any decent POSIX support, I could just do:
select(file_count, files_waiting_for_read, NULL, files_waiting_for_excpt, NULL, NULL);
And select will return when there's anything interesting on some of the files. Windows doesn't support select or poll. Fine. I figured I could take the file and do something like:
The above loop would exit when more data is available to be read. But nope, Windows doesn't have an equivalent of eof() either! I could possibly call ReadFile() on the file, and determine if it's at the eof that way. But, then I'd have to handle the reading at that point in time -- I'm hoping to simply be able to figure out that a file is readable, without actually reading it.
What are my options?
