防止转储核心文件？ [英] prevent dumping core file?
问题描述
你好，
我正在linux系统上编写一个c程序。我正在调试分段
故障，但我不希望它转储核心文件，因为该程序的内存足够
足迹超过300Mb我不喜欢每次我添加一个新的printf语句来调试代码时，都不需要它来生成一个
300Mb的文件。
我可以做些什么来阻止它从倾销核心文件，即使它是
seg fault？ （这是unix / linux的东西，还是ac的东西？）
谢谢！

这确实是一个linux的事情。 C与转储核心
文件无关。
linux内核写出一个包含
终止进程核心映像的文件当收到某些信号时。核心图片
文件在进程的工作目录中写成
。有关更多信息，您可以
查看核心的手册页。
为了防止它转储核心文件，您可以创建一个目录
名为
" core"在你的工作目录中。
hello,
i''m writing a c program on a linux system. i''m debugging a segmentation
fault but i don''t want it to dump a core file because the memory
footprint of the program is over 300Mb and i don''t need it to generate a
300Mb file every time I add a new printf statement to debug the code.
can i do something to prevent it from dumping the core file even when it
seg faults? (is this a unix/linux thing, or a c thing?)
thanks!

It''s a Unix/Linux thing.
It is indeed a linux thing. C has nothing to do with dumping a core
file.
The linux kernel writes out a file containing a core image of a
terminated process when certain signals are received. The core image
file is written
in the process''s working directory. For more information you may
see the man page of core.
To prevent it from dumping the core file,you may create a directory
named
"core" in your working directory.
