Function svn_path_compose 

pub unsafe extern "C" fn svn_path_compose(
    components: *const apr_array_header_t,
    pool: *mut apr_pool_t,
) -> *const c_char

Join an array of const char * components into a ‘/’ separated path, allocated in @a pool. The joined path is absolute if the first component is a lone dir separator.

Calling svn_path_compose() on the output of svn_path_decompose() will return the exact same path.
