The warning message is "Possible misuse of comma operator here" and
the offer to fix is issued in the Xcode IDE. The option being set is
"CLANG_WARN_COMMA" per the project configuration help. Setting it to
NO is also an option. I'm not sure what the default is supposed to be
and it appears it's not documented by Apple yet for Xcode.
 
This is in fact a C file, not C++ and I posted in the wrong group,
sorry about that.

Thanks. I like this better than maintaining the idiomatic use.

It's a text file. The usage appears twice, counting the file
characters first, allocating memory, then rewind and load the file
into the allocated buffer.

Indeed it is. That's why I was surprised when the warning showed up in
previously valid code. It seems Apple decided to set the default in
Xcode to warn about suspicious comma usage. I created a new "hello
world" project from the GUI and it defaults to CLANG_WARN_COMMA = YES.
This is in the "all languages" section of the Xcode project settings
so they have chosen to apply it universally.

>Do you mean implement only the UI for each platform?
 
If you watch the video (I suspect Mr. KILLFILE has not), you'll see
that they attempted initially to do what he suggested but found that
they were duplicating lots of view logic, hence they ended up with the
view logic in the cross-platform C++ side of things and only added a
thin veneer of delegating UI code for each platform.

The DropBox team was not large, but it certainly wasn't one person.
They had already done the complete duplicate-the-entire-app between
iOS and Android and for their next version were determined not to
repeat that mistake and duplicate as little as possible between
platforms. This is (a positive) real-world experience and worth
watching and understanding, even if you disagree with their approach.
 
That's why I suggested it may be of interest to you. You are, of
course, free to ignore it.

It is in a C context. I managed to post the question in the wrong
group somehow. It is a text file opened with "rt" flags in the fopen
call.

Not everybody will be saved, Daniel.
 
Evidence comes from the spirit. A person cannot come to Jesus unless
they are drawn from within by God. Once they are drawn they ask Him
to forgive their sin, they are forgiven. This restores them to a
right-standing with God, and the punishment of sin (spiritual death)
is taken away. This makes them alive again in the spirit, born again.
 
They are still attached to this old man flesh, but their existence is
augmented by the new thing. It is from within that new augment that
God is able to prove Himself to each person. The term you hear people
say is they "know that they know that they know" that they're saved.
It is not from natural senses, but is from the spirit.
 
There are also evil spirit influences in this world, which lead people
continually to sin. They can also give a person a "spiritual feeling,"
but it does not last, and is not naturally moving toward Jesus Christ.
 
This is the truth, Daniel. You do not know it because you are not
seeking for the truth. You are standing in your arrogance and pride
believing you are correct, shooting down things I would teach you
about Christianity. That inability you have to seek the truth is why
you are not drawn by God to it, because God only draws those to find
the truth who are truly seeking for it.
 
Good day, Daniel.
