Can anybody tell me what those lines do, or correct me?

If we find one of those strings in the line that 'buf' gives us, and the 
 address of the where this string is beginning is successfully stored 
in 'str'...

we check if the value to which *str points, is not NULL and not between 
0-9 if so...

call lockout() with some address which is now higher (where does it 
point to now ?)

if not we leave the while-loop.

what does str really contain? I'm afraid i understand it completely wrong.
str should  point to the beginning of the string we were looking for 
with strstr(), thus using str, cannot let me do something which located 
before the occurrence of "Failed...."?
