c++ - Windows: File rename and directory iteration clash -


I am using boost :: filesystem to rename a file like this: 

  boost :: filesystem :: rename (tmpFileName, targetFile);

tmpFileName / targetFile type :: boost :: filsystem :: path

While doing this, I use this code on a directory in another thread : 

  directory_iterator end_itr; (Directory_iterator itr (dirInfoPath); itr! = End_itr; ++ IRR) {path currentPath = itr-> Path (); If (is_directory (itr-> (state ())) {// Skip Directory} Other {std :: string file_name = currentPath.leaf (); If (! Boost :: algorithm :: starts_with (file_name, "new") & amp;! Boost :: algorithm :: begin_with (file_name, "finished") and boost :: algorithm :: ends_with (file_name, " .info ")) {// The saved filename is correct in some variable returns; }}}

When this code is executed, I get an exception to rename: 

  boost :: filesystem :: rename: process File can not be accessed because it is being used by another process

Is it possible that the recurrence and renaming operations collide, because they both use Directory Inodes, Or do I have some more problems?

The code you provided does not have any file open operation, so it lock file. You iterate over the directory and rename the file , right? It is therefore possible that this file is actually used by another application such as file viewer or something else, this is a fairly common error or you have opened it in your app elsewhere

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....
