c++ - How to use a UNIX socket in a CGI program -

-

I want to write a web interface for a program that has a Unix Socket based server interface, but it seems that it is impossible To connect it successfully within the CGI program.

I looked at the httpd.conf file and searched the web, but nothing was found. The CGI program C ++ is written in the Unix Socket path accessible by the httpd server.

A customer to connect to a unix local socket, you first create an anonymous socket, like For TCP: 

  int fd = socket (AF_LOCAL, SOCK_STREAM, 0);

Then you create the appropriate struct sockaddr_un with the destination path: 

  struct sockaddr_un addr; Addr.sun_family = AF_LOCAL; Strcpy (addr.sun_path, "/ path / to / server / socket / file");

and call connect () : 

  connect (FD, (struct sockaddr *) & amp; addr, sizeof ( Addr));

However, it is widely documented on the pages of all humans and online. There is no C ++ specific method, unless you use third party libraries; These are the Nix-specific extensions for standard C: 

  #include & lt; Arpa / inet.h & gt; #include & lt; Netinet / ip.h & gt; # Include & lt; Sys / socket.h & gt; # Include & lt; Sys / types.h & gt;

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
