using "use_first_pass", but how?

[ingo]

Hello everybody on this list! 
 
My problem: 
I have to write a module, that needs the previously entered password. To 
prevent a second prompting from the user for the password i would like to 
implement the "use_first_pass" functionality provided by other modules (to 
be able to stack the new module into the current setup). The current 
problem right now is that i don't really know how to access these data 
inside my custom module. 
I read already the whole "module writers guide", but i didn't found any 
hints to do this.  
And next, as i've read the source for pam_unix and if i understood it 
right, it is not storing the entered password, and therefor i can't use 
this. 
Maybe someone can help me or explain it to me. 
Thanks in advice
