*push-error-using-command*（AutoLISP）

签名

(*push-error-using-command*)

没有参数。

返回值

类型：T

返回的值 ofis。T

言论

应在定义包含函数使用的自定义处理程序函数后调用 。*push-error-using-command**error*command

使用时，您只能访问全局变量，而不能访问自定义处理程序中发生错误的函数中定义的局部变量。如果需要访问局部变量，请将函数的任何实例替换为函数和调用。*push-error-using-command**error*commandcommand-s*push-error-using-stack*

例子

下面的示例演示函数的用法。*push-error-using-command*

(defun my_err (err_msg)
    (if (/= err_msg "Function cancelled")
      (prompt (strcat "\nError: " err_msg))
    )
    (command "._undo" "_e")
    (command "._U")
    (setq *error* olderr)
  (princ)
)

(defun myUtil (key / )
    (setq olderr *error*
              *error* my_err)
    (*push-error-using-command*)         ; Indicate use of Command function instead of Command-s
                                         ; in the custom error handler

    (command "._undo" "_group")          ; The following will not be executed in this sample, but is good 
                                         ; framework for setting up your own error handlers
  
    (/ 1 0)                              ; Call a function with incorrect values to trigger the custom error handler
                                         ; Remove when setting up your code
   
    ;; Perform your tasks here

    (command "._undo" "_e")
    (setq *error* olderr)                ; Restore old *error* handler
    (*pop-error-mode*)                   ; End the use of *push-error-using-command*
)

加载示例代码后，在命令提示符下输入（myutil“字符串”）以输入错误处理程序。
