error_desc [result] 这样用对么

ssb

check.lua

function check (result)
  if result ~= error_code.eOK then
    error (error_desc [result] or
           string.format ("Unknown error code: %i", result),
           2) -- error level - whoever called this function
  end -- if
end -- function check

return check


红字部分用法可对？ error_code ,error_desc在check.lua里都没有定义,
这两个是怎么个意思呢

这些我理解
我想问 error_code和error_desc是默认的表还是自定义的表，还是别的什么

The "error_desc" table is automatically supplied by MUSHclient for Lua scripts.

I wasn't sure whether I could access error_code and the others without importing constants.lua first (which is really wrapped by XML). Now I see error_code is an entirely separate table, and it seems that I can access it, so thank you for letting me know!


error_code也找到了
多谢ddid了！
