我的控制台输出在哪里？ [英] Where did my console output go?
问题描述
您好，
我正在编写使用DLL的代码，该代码应打印到
控制台
一些有用的信息，但由于某种原因，它没有这样做。
环境
解释起来有点复杂但在这里：
- 我正在使用一个名为SYMPHONY的C库，我自己编译。
在标准控制台应用程序中使用那个
库时，我得到控制台输出
吧。
- 我在C中为库编写了一个包装器，通过
mex-files将它挂钩到Matlab（
是编译到的C文件DLL，但名称不同）
- 这个包装器与库一起用于Matlab
程序。来自内部
Matlab SYMPHONY输出没有出现。
- 这个Matlab程序被编译成.NET组件，当
在Visual Studio中使用的
a控制台应用程序显示了上一步中
中缺少的所有信息
。
由于我不明白这里发生了什么，我想
来写
有时出现在控制台中的所有信息（并且
有时候没有）
到一个文件，但是不需要修改我建的
的SYMPHONY库
第一步。
C标准库中有什么东西能帮助我这个吗？
提前致谢，
CarlosMartínez

否。这种情况属于你的窗口系统领域，而不是

这太荒谬了。你假设他可以阅读它，只是因为他有一个西班牙裔美国人的名字，你假设我们不能只是因为
$ b而读它$ b - 实际上并不清楚你为什么做出这个假设，但我在
至少有一个反例。从他发来的消息，唯一的语言
你可以肯定他精通英语，而且他看起来很流利。
流利的。

AllocConsole（）;
他对此非常具体：他要求一个C标准库
函数。 AllocConsole（）不在C标准库中。你没有回答他问的问题，你回答了你自己设计的另一个问题。

windows no crean una consola。
即使他要求获得特定于Windows的答案，而不是C→
标准库答案，你仍然会做他一个更好的服务
通过将他的查询重定向到一个专门讨论他使用的系统的论坛。在那个论坛上，他有比他在这里更好的机会
听取别人的意见，无论你的建议是否有意义。
Hello,
I am writing code that uses a DLL which is supposed to print to
console
some useful information but for some reason it is not doing so. The
environment
is a bit complex to explain but here it goes:
- I am using a C library called SYMPHONY, which I compiled myself.
When using that
library in an standard console application I get the console output
right.
- I wrote a wrapper for the library in C to hook it into Matlab via
mex-files (which
are C files compiled to DLLs, but with a different name)
- This wrapper altogether with the library is used in a Matlab
program. From inside
Matlab the SYMPHONY output doesn''t show up.
- This Matlab program is compiled into a .NET component which when
used by
a console application in Visual Studio shows all the information i was
missing in
the previous step.
Since I am not understanding what is going on right here I would like
to write
all the information that sometimes appears in the console (and
sometimes not)
to a file, but without the need to modify the SYMPHONY library that I
built in
the first step.
Is there anything in the C standard library that can help me with
this?
Thanks in advance,
Carlos Martínez

No. That kind of thing is in the domain of your windowing system, not
the C standard.

Answer in Spanish so the pedants in this group do not get it!That''s ridiculous. You''re assuming he can read it, just because he''s got
a Hispanic name, and you''re assuming that we can''t read it just because
-- it''s not actually clear why you''ve made that assumption, but I''m at
least one counterexample. From the message he sent, the only language
you can be certain that he is fluent in is English, and he seems fairly
fluent in it.
Lo mejor que puedes hacer es llamar la funcion
AllocConsole();He was very specific about this: he asked for a C standard library
function. AllocConsole() is not in the C standard library. You did not
answer the question he asked, you answered a different question of your
own devising.
cuando comienzas tu programa. Esto va FORZAR la existencia de una
consola. Probablemente sabes ya que programas utilizando solamente
windows no crean una consola.Even if he had asked for a Windows-specific answer, rather than a C
standard library answer, you would still have done him a better service
by redirecting his inquiry to a forum devoted to the kind of system he''s
using. In that forum, he''d have a better chance than he has here of
hearing from someone else whether or not your advice makes any sense.
