the C++ file stream behavior wrt openmode is not intuitive at least not to me . so my code was not behaving properly . as a result i tested its behavior with every combination of openmode values . ChatGBT was nice enough to write the combination generating code for me . so i now have a compendium of results to rely on and can now find the correct openmode values required for any situation .

Write a Tip?

thank you for the suggestion . however my previous tips have always been removed as inconsequential . the code is simple enough . no doubt you can write it in no time at all . if you do not wish to bother with it i can provide same via DropBox as i do not have a Git account and have yet to learn how to utilize it .

What exactly is not intuitive about those modes?

As I'm not a regular C++ programmer I once had a similar problem, it was not clear to me the stream was written in text instead of binary format. Took me a very long time to find out what the problem was ...

I guess my background from assembler and other base languages helped me with it.

opening an existing file w/ ios_base::out causes its contents to disappear .
to write to a existing file seekp'ed position requires ios_base::in | ios_base::out .
to write to a non-existing file seekp'ed position requires ios_base::out .

Yes, but that follows the basic IO model from C (OPEN, READ, fopen, fread etc.), and the Windows API (CreateFile, ReadFile ...). All use the same basic concepts, and the difference between writing binary data and text has always been there.

I hate that they cook text. I hate it so much.

I once spent an entire day debugging my TTF engine because the IoT code I was using was opening my font file in text mode.

The thing is, 90% of it worked.

Well, I guess we have all been there at one time or another.

CreateFile offers many options . all intuitive . how can deleting the contents of a file for output be intuitive . how can requiring read privileges in order to write be intuitive . never mind it is part of this or that IO model .

That's why you should always study the documentation.

the documentation for openmode::out :
"out open for writing"
doesn't Howard Wolowitz do something w/ documuntation .
