问题描述
我是线程的新手，但对c来说一般都很好。我正在尝试运行一个可能需要一段时间的程序，但系统本身并没有返回
，直到程序完成。我认为线程可以工作，因为我可以发送系统在一个线程上运行然后继续该程序。我试图尝试
，但它看起来就像只运行系统一样。 byu
本身，但它给了我一个分段错误并退出。有人可以请
告诉我如何正确地做到这一点吗？
哦，如果重要的话，我试图在gtk回调中做到这一点。
tia，

天哪，男人，不要''你知道C咒语：K& R使用1-CPU
机器，所以它将适用于所有我们的后代，现在和永远，
amen。
没关系，沃尔玛最便宜的电脑将很快成为双核AMD的价格。
但是要回答你的问题，你不能用线程来做，你只需要用bb或者某些东西拆掉一个单独的进程。或者在
Unix / Linux上将一个&符号放在你传递给命令的结尾处
system（）。

我从来没有听说过这样的口头禅也不知道它是如何适用的
自
原始海报并没有说他在一台机器上工作的价格比一台CPU的价格高一些。
无论如何帖子绝对不在这里。 Poly man I
认为
专用于您的操作系统的新闻组最多可能是

直到程序完成。我认为线程可以工作，因为我可以发送系统在线程上运行然后继续该程序。我试图尝试，但它看起来就像只运行系统一样。 byu
本身，但它给了我一个分段错误并退出。有人可以告诉我如何正确地执行此操作吗？
哦，如果重要的话，我正在尝试在gtk回调中执行此操作。
天哪，伙计，你不知道C咒语：K& R使用1-CPU
机器，因此它将适用于所有我们的后代，现在和永远，
amen。
这甚至都不接近C口号。
别介意沃尔玛最便宜的电脑很快就会成为
双核AMD。
C：双核AMD的首选语言。
但是为了回答你的问题，你不能用线程来做，你会...... / b
必须分开一个单独的进程，用fork或者某些东西。或者在
Unix / Linux上将一个&符号放在你传递给命令的结尾处
system（）。
那更像是它。

I''m a total newbie to threads, but am generally good with c. I''m trying to
run a program that might take a while, but system by itself does not return
until the program is finished. I thought that threads would work, because I
could send system to run on a thread then continue with the program. I
attempted, but it seems too act exactly like just running "system" byu
itself, but it gives me a Segmentation Fault and exits. Can someone PLEASE
show me how to do this correctly?
Oh, and if it matters, I''m trying to do it within a gtk callback.
tia,

poly-p manHeavens, man, don''t you know the C mantra: K & R worked with a 1-CPU
machine, and so it will be for all us descendants, for now and forever,
amen.
Never mind that the cheapest computer at Wal-MArt will soon be a
dual-core AMD.
But to answer your question, you can''t do that with threads, you ''ll
have to spin off a separate process, with fork or somesuch. Or on
Unix/Linux put an ampersand on the end of the command you pass to
system().

Heavens, man, don''t you know the C mantra: K & R worked with a 1-CPU

amen.I''ve never heard of such a mantra nor do I see how it is applicable
since
the original poster did not say that he works on a machine with more
than
one CPUs.
Anyway the opening post is definitely out of topic here. Poly man I
think
that a newsgroup dedicated to your operating system will be the most
likely
to be of assistance.

That''s not even close to the C mantra.

dual-core AMD.
C: the language of choice for dual-core AMDs.

That''s more like it.
