To quote the docs (copy/paste)
int entries ()
Returns the number of entries (name/value pairs) in a group.
Make the docs read
Returns the number of entries (name/value pairs, comments and empty
lines) in a group.

Yes confusing because the docs make no mention of comments and empty
line to avoid the confusion.

The docs say
const char * entry (int index)
Returns the name of an entry.
And an empty line has no name as you state above. Perhaps the doc
should say that and in the case of an empty line, what the returned
char * will be. (NULL I suppose)

There is no mention that a name can not be numerical, the name is just
a string as is "abc". I do not see your point or why you even mention
it.

I had thought of you points 1 - 3 and decided that it is messy and
would not give me what I set out to do. I ended up downloading third
party source code and adding a couple of functions to get exactly what
I want. The source code is in ANSI C so it is very portable.
