C# Multi-threaded app - structure?

由 送分小仙女□ 提交于 2019-12-10 13:58:45
问题 So, I'll make an application for checking links if they're accessible(live). My question is how to make the threads "always busy". What I mean: The app run 100 threads(created with FOR loop for example) with 100 different URLs. So when 1 of the threads finish it's job(check if URL is available) to get new URL and start again immediately. So the 100 threads will work non-stop till all URLs are checked. How can I accomplish that? 回答1: What you are looking for is called the Producer-Consumer

Returning multiple data items from a function in C or C++

由 ♀尐吖头ヾ 提交于 2019-12-10 12:53:28
问题 I am confused on a couple homework questions I have... Can you return multiple data items from a function by using return()? Can a function only return one value, unless it is a pointer to an array? I believe that the answer is that a function can return multiple data items by returning a structure. Then, returning a pointer to an array is not the only way - if that is a way? But there seems to be a lot of discussion on this topic and so I want to make sure I have at least the basic idea

问题 Whe I run it fgets() is simply ignored and scanf() doesn't input data to structure. My code: #include"stdio.h" #include"stdlib.h" typedef struct { char nazv[50]; int numr; int date[3]; int time[2]; } train; void input(train*rasp,int n); void print(train*rasp,int n); void output(train*rasp, int n, int*date, int*time); main() { int n; int t[2]; int d[3]; printf("How much? "); scanf("%d",&n); train* rasp=(train*)malloc(n*sizeof(train)); input(rasp,n); printf("Enter date: "); for (int date=0;date

wordpress multisite remove /sites/{ID}/ automatic upload url

由 被刻印的时光 ゝ 提交于 2019-12-10 11:16:37
问题 when using wp multisites it gets messed up pretty fast. Is there any solution available removing the automatic /sites/{id}/ folder structure? I'm able to adjust the site-upload-dir within site-settings but it always adds " /sites/{id}/ " to the uploaded file through the media-manager. Is there any snippet available removing/disabling these extra folder structure? 回答1: First I ended up changing the core in wp-includes/functions.php in order to disable the addition: if ( defined( 'MULTISITE' )

Managing Multi-Project Branches in Git

问题 Are there tools to achieve the following abstract operations in a Maven project/SCM scenario? Given an application project, create branches for the application and all the snapshot libraries that it uses, transitively; these branches should be manageable as one logical branch (see next) Given the logical branch of an application project, release it (by running Maven release); this means releasing multiple branches, one per library Background (original): As you know, Git recommends using the

What mysql engine for huge amount of data (logging)?

问题 What mysql engine would be best suited for handling huge amount (many rows) of (small) data? I talking about logging. I'm thinking about logging whenever I do things on my page, like calling a function, calling a file and so on. A tip of how I should structure the table is also appreciated. 回答1: The Archive storage engine is geared toward storing logs, and is compressed. It supports INSERT and SELECT only, no UPDATE or DELETE. I have never used it, but it may fit your needs. 来源： https:/

问题 Is it allowed to use same name structure with different definitions in 2 different c files in the same project. For eg. File1.c typedef struct { unsigned int unVar; } abc; File2.c typedef struct { int var; } abc; abc is used in both the files. When i compile these file as part of same project there are no errors, but i want to understand whether this is correct usage. 回答1: 6.7.2.1 Structure and union specifiers The presence of a struct-declaration-list in a struct-or-union-specifier declares

The construction method is different from BRepPrimAPI_MakeBox. In the paper construct the box from vertex, edge to solid, while in BRepPrimAPI_MakeBox from solid, shell to vertex. From the construction, the BRep data structure in OpenCASCADE also can be called the Winged-Edge data structure. Key Words. OpenCASCADE, BRep, Box, The Winged-Edge Structure 1.
