Hi Norbert, hi all,

OK, I recognize 'BUFFERLEN-strlen(x)' is always plus.
Even when buffer is full, strlen(x) become BUFFERLEN-1,
because buffer includes '\0'.
Sorry. Please forget my previous mail.
I'll attach my test source.
Hi Norbert, hi all,
-#define TAIL(x) (x+strlen(x))
+#define TAIL(x) ((x)+strlen(x))
It was my fault. Thank you for correcting.
+#define TAIL_LEN(x) ((x)+strlen(x)), (BUFFERLEN-strlen(x))
Nice idea.
I'm not sure but I'm wandering if snprintf()
can handle negative (minus) length or not.

Done, fixed patch attached: mendex-bugfix

Done that for fwrite.c, but there are other cases in the source.

Ok, will do that.

I am not sure who is currently maintaining mendex,

Please apply whatever patch you see fit.

Dear all,
I hope there is still someone listening.
Since quite some time there is a bug in mendex.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=534641
Easy to reproduce:
With the following idx file:
\indexentry{foo|(}{1}
\indexentry{foo|mac}{1}
\indexentry{foo|)}
6 matches
