Function svn_fs_lock 

pub unsafe extern "C" fn svn_fs_lock(
    lock: *mut *mut svn_lock_t,
    fs: *mut svn_fs_t,
    path: *const c_char,
    token: *const c_char,
    comment: *const c_char,
    is_dav_comment: svn_boolean_t,
    expiration_date: apr_time_t,
    current_rev: svn_revnum_t,
    steal_lock: svn_boolean_t,
    pool: *mut apr_pool_t,
) -> *mut svn_error_t

Similar to svn_fs_lock_many() but locks only a single @a path and returns the lock in @a *lock, allocated in @a pool, or an error.
