big tarfiles to lex

I've very big tar-files with eMails in it.
My lex-Programm should work with the content of these files.
The Problem: When I pipe it to lex like this:
more tarfile | lexprogram >output
it ends with a broken pipe.
When I try it like this
lexprogram <tarfile >output
the program will abbort after the same time (I guess yywrap stopps the program).

Hm, shouldn't you first extract your tarfile?

Something like:
cd /tmp/mydir
tar -xf /path/to/my/tarfile.tar
cat * | lexprogram

(The last line should probably be a loop for each of the files if there are really MANY files. The loop depends on the shell).

tar files contain null bytes (0x0). Most lex flaviours treat this as an EOF. Your must take care for them before the default action (.)
Check your lex manual, or switch over to flex (which can handle null bytes ;-)
