getopt help required

[Rishi]

suppose i have a program in which there are two arguements 'a' and 'b'

the program is such that i will work iff
-either 'a' or 'b' is present as an option to it
-both 'a' and 'b' cant be present sameltaneously
-either of the two should be there

I want to know is there any way in the function getopt or getopt_long
that can help me in doing this


Thanks in advance

Well, I'm not sure this is on topic here (comp.unix.prog rammer might be
better), but AFAIK getopt can set a boolean flag on encountering an
option; just do this, and check afterwards your conditions against the
two flag-variables and take appropriate action.

Off topic. Not portable. Cant discuss it here. Blah, blah, blah.

I've got an options parser on my website that may do what you want.

getopt is not part of the language, it's a Posix library function, so
it's not really on-topic here.


Depending on whether you really want the Posix version or the GNU
variant, you'd need to look in slightly different places.

As far as I can see from a brief examination, neither provide an easy
way of making options/arguments mutually exclusive.
