Rely on string in const struct pam_message?

[Dan Behman <dbehman ca ibm com>]

Hi,

I want my application to be non-interactive
so I'm coding my own converation function that will interact with the PAM
modules...  My question is, can I safely do string comparisons on
the msg string member of the pam_message structure to decide what responses
my converation function will send back?

In other words, are the existing string
messages sent to an app's conversation function written in stone and expected
to not change?  Or perhaps I'm going about this all wrong...

Thanks,
Dan Behman..
