On Linux, why does the destructor run twice on shared instance of global variable in C++? -


On Linux I have generated some C ++ code from a static library that defines global variables. An example of this global variable is shared between two shared libraries, which refers to its symbol.

When the process is closed and the static ending phase is run, I see that the destroyer is run twice at this shared frequency! Probably every time the library is unloaded.

This question is closely related to the other. I recently seen here:

Does anyone know the theoretical interpretation behind this behavior?

If you take a nude indicator and put it in smart pointer (twice), then Will be destroyed twice, once for every container refractor, falling from zero.

So, if you pass a nude pointer in both libraries, then it can do it, each person puts it in a shared indicator object and destroys each of them. If you can see the stack backatas during dtor, then it should be shown happening in both libraries.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
