Hello All,

     I  debug code of clamav.  Aho-Corasick( AC) Algorithms concepts for
matching between virus and signature files. Step for AC is build trie (
keyword tree)  for inserting signature from virus database files. I  
have question in step build tire before matching with input information.
Why source code in "static int ac_maketrans(struct cli_matcher *root)"
[1]  define size of array is 256?.
      In addition, Do you using the Depth First Search Algorithm( DFS)
for building trie?

Thanks you,
Chatsiri Rattana
