I guess it makes sense when you send me the code and give the line number

suggestion in the course of the day.
One important thing you need to think about is that pMsg does NOT necessarily
use cstr objects to represent the entities. For example (IIRC), raw message
is kept in a different buffer, and you cannot use cstr methods on that
buffer. %msg% is actually not stored at all, it is taken from rawmsg. There
is a whole lot of this kind of optimization done inside the message object. I
guess this is what is hitting you.
Ok, that makes sense. so should I just insert a \0 at the appropriate
place and decrament the iLenRawMsg and iLenMSG values?

Rainer,
I'm testing the cisconames parser, and I've almost got everything
working (it looks like a total of 2 bugs in the initial code I sent
you),
but I'm running into problems trying to truncate a string.
in the message parser, what would I pass to rsCStrTruncate() to
tuncate
2
characters from the incomeing message?
I've just checked the code. It's the number of characters to
truncate. So you
need to pass in "2".
Code in question:
http://git.adiscon.com/?p=rsyslog.git;a=blob;f=runtime/stringbuf.c;h=f4
a9caae
d62d7ad9bca0deaf4728298cc40b5c2d;hb=HEAD#l435
the problem I'm having is figuring out what to use for the pointer to
the
string. so far everything I've tried is wrong and results in a
segfault.
I'm assuming that the right answer is pMsg->something, but I haven't
figured out what the something is.
