Function svn_fs_node_relation 

pub unsafe extern "C" fn svn_fs_node_relation(
    relation: *mut svn_fs_node_relation_t,
    root_a: *mut svn_fs_root_t,
    path_a: *const c_char,
    root_b: *mut svn_fs_root_t,
    path_b: *const c_char,
    scratch_pool: *mut apr_pool_t,
) -> *mut svn_error_t

Determine how @a path_a under @a root_a and @a path_b under @a root_b are related and return the result in @a relation. There is no restriction concerning the roots: They may refer to different repositories, be in arbitrary revision order and any of them may pertain to a transaction. @a scratch_pool is used for temporary allocations.

@note Paths from different svn_fs_t will be reported as unrelated even if the underlying physical repository is the same.
