NAME

       mtree_init, mtree_free - initialize and free a merkle tree

LIBRARY

       Librecast library (liblibrecast, -llibrecast)

SYNOPSIS

       #include <librecast/mtree.h>

       int mtree_init(mtree_t *tree, size_t sz);
       void mtree_free(mtree_t *tree);

       Compile and link with -llibrecast.

DESCRIPTION

       The  tree_init function initializes the merkle tree structure tree with base data size sz.
       sz is the size in bytes of the base file or data which will be used to build the  tree  by
       calling mtree_build(3).

RETURN VALUE

       mtree_init()  returns  zero  on  success.   On  error, -1 is returned, and errno is set to
       indicate the error.

       The mtree_free() function returns no value, and preserves errno.

ERRORS
