Function svn_wc_is_adm_dir 

pub unsafe extern "C" fn svn_wc_is_adm_dir(
    name: *const c_char,
    pool: *mut apr_pool_t,
) -> svn_boolean_t

Return @c TRUE if @a name is the name of the WC administrative directory. Use @a pool for any temporary allocations. Only works with base directory names, not paths or URIs.

For compatibility, the default name (.svn) will always be treated as an admin dir name, even if the working copy is actually using an alternative name.
