In the "Text files" paragraph)
If you don't read before the while(!feof(f)) then it is broken since the EOF flag does not get set until after a read has been done.

Is there any clear documentation on the binary formats used to serialize the various MFC data structures? I've been able to view some of my own classes in a hex editor and use Java's ByteBuffer class to read them in (with automatic endianness conversions...

I agree with jmatthias: use the MFC source code.

The writer process might write to the pipe a couple ... .
Then you can read a single packet by reading four bytes, converting that to an integerYour assumption that a read will execute immediately after a write is not true.

This is something I have only just become aware of in my own reading. That thing where you no longer read as a reader - no longer read free from textual analysis. No longer read for fun. And God, I miss it. But since taking my writing seriously, analysing...
