NAME

       mdex_tree_hash - create hash of merkle tree root

LIBRARY

       Librecast library (liblibrecast, -llibrecast)

SYNOPSIS

       #include <librecast/mdex.h>

       int mdex_tree_hash(unsigned char *hash, size_t hashlen, mtree_t *mtree, size_t n);

       Compile and link with -llibrecast.

DESCRIPTION

       The  mdex_tree_hash  function  creates  a  hash of length hashlen from the root node of mtree with key n.
       This is used to index an mtree in several parts, and to distinguish the root node  from  the  first  data
       node when nodes = 1.

RETURN VALUE

       The mdex_tree_hash() returns zero on success.  On error, -1 is returned.
