crashpad integration

[digrand...@gmail.com]

Hi everyone,
I know there is many documentation on source code for crashpad, but is there any documentation, or example of how to integrate it in an application?
I fail all my try . When I start handler, an error message occured and the return of method is false.
[5204:8288:20180403,152110.161:ERROR registration_protocol_win.cc:84] TransactNamedPipe: Le canal de communication a ├®t├® ferm├®. (109)
I 'm trying to explore chromium but i can't generate solution from command " gn gen out\Default --ide=vs ".
This is my code to start handler:

#include "stdafx.h"
#include "Person.h"
#include "client/crashpad_client.h"
#include <string>
#include <map>
#include <vector>


int main()
{

crashpad::CrashpadClient client;
#ifdef _DEBUG
const base::FilePath handlerPath = base::FilePath(L"C:\\workspace\\crashpad\\crashpad\\out\\Debug\\crashpad_handler.exe");
const base::FilePath databasePath = base ::FilePath(L"C:\\workspace\\crashpad\\crashpad\\out\\Debug\\crashpad_database_util.exe");
const base::FilePath tempDir;
#else
const base::FilePath handlerPath = base::FilePath(L"C:\\workspace\\crashpad\\crashpad\\out\\Release\\crashpad_handler.exe");
const base::FilePath databasePath = base::FilePath(L"C:\\workspace\\crashpad\\crashpad\\out\\Release\\crashpad_database_util.exe");
const base::FilePath tempDir;
#endif


if (client.StartHandler(handlerPath, databasePath, base::FilePath(), std::string(), std::map<std::string, std::string>(), std::vector<std::string>(), true, false))
{

}


return 0;
}
Thanks for your help.

Hi Fabien,

The main thing that looks wrong there is that databasePath should be a path to an possibly-not-yet-existing directory, not the path to the database utility tool. The database path is where Crashpad stores crash reports and user settings.

Hi, thanks for your help, I made modifications and now, I can create a client correctly. My next step is to create a minidump when my application crash. I know that I'm close to reach the goal.
See you
Fabien

If StartHandler() is succeeding, then Crashpad is set up correctly and crashes should be getting caught. If your process crashes, you should see crashes in the database directory you provided at initialization.

You can inspect the directory directly to see if there's a .dmp file there (on Windows), or more generally use crashpad_database_util to inspect the database.
