Description

I met an issue when reading from the shell-command:

I have implemented the sharing of terminal command feedback results among multiple processes using shared memory.

However, this shared memory is used to store strings. How large should I set it to be appropriate?

• If it is too large, it will face the issue of wasting memory resources. If users execute multiple lightweight terminal commands simultaneously, it will incur considerable overhead.
• If it is too small, when obtaining lengthy terminal feedback, it may lead to buffer-overflow problems.

TODO

• which value is better?
• is there any other ways to set it ? like in constructor(), provided by users ?
