Lisp中的当前内存使用情况 [英] Current memory usage in Lisp

问题描述

我需要从Common Lisp程序中找出当前正在使用多少内存.

I need to find out, from within a Common Lisp program, how much memory is currently being used.

我了解没有一种可移植的方法(标准功能room以文本形式将信息打印到标准输出中，而不是将其作为值返回)，但是sb-kernel:dynamic-usage在SBCL中工作.

I'm given to understand there is no portable method (the standard function room prints the information to standard output in text form instead of returning it as a value), but sb-kernel:dynamic-usage works in SBCL.

其他Common Lisp实现中有哪些等效项?还是有其他方法可以解决这个问题?

What are the equivalents in other Common Lisp implementations? Or is there another way to solve this problem I should be looking at?

推荐答案

它可能对您没有多大帮助，但无论如何:

It may not help you much, but anyway:

您可以捕获(房间)的输出并进行解析.

You can capture the output of (room) and parse it.

(with-output-to-string (*standard-output*)
  (room))

上面返回的字符串为ROOM输出.

Above returns a string with the output of ROOM.

另外，通过对标准unix命令的外部调用(如果您在Unix上)，可能有助于请求进程的内存大小.

Additionally it may help to request the memory size of the process via an external call to a standard unix command (if you are on Unix).
