ARGP: Documentation of

[Robert Hairgrove]

Hello,

I am writing some little C++ wrapper classes for the argp functions.
Unfortunately, I cannot find any documentation of the argp_child::flags
member, i.e.: what possible values it could have. The only documentation
seems to be the one line comment in argp.h: "Flags for this child", which is
slightly less than helpful...

One would think that it might take the same values as the flags argument to
the main argp_parse() function; however, that argument is unsigned, whereas
the argp_child member is declared as an int.

I noticed that the author of the argp library, Miles Bader, sometimes comes
here ... but I would be grateful for anyone's advice here. Thanks!
