This directory contains client code for collecting and sending minidumps.
|
||||
You can use them in your project as follows:
|
||||
|
||||
exception_handler.lib:
|
||||
|
||||
This library should be linked into the application from which you want
|
||||
to collect crash reports. See the comments in exception_handler.h for
|
||||
instructions on setting up the handler to write minidumps on crash.
|
||||
You can also use ExceptionHandler to write non-crash minidumps.
|
||||
|
||||
When linking with this static library, you will need to also link with
|
||||
rpcrt4.lib and ole32.lib.
|
||||
|
||||
crash_report_sender.lib:
|
||||
|
||||
Typically, after catching a crash, you will launch an external application
|
||||
to collect any additional information from the user, and upload the report to
|
||||
the server. CrashReportSender is a utility class that can be used when the
|
||||
data is ready to upload.
|
||||
|
||||
When linking with this static library, you will need to also link with
|
||||
wininet.lib.

// ExceptionHandler can write a minidump file when an exception occurs,

//
|

// To have the exception handler write minidumps when an uncaught exception
|

// (crash) occurs, you should create an instance early in the execution

// of your program, and keep it around for the entire time you want to
|

// have crash handling active (typically, until shutdown).
|

//
|

// If you want to write minidumps without installing the exception handler,

// you can create an ExceptionHandler with install_handler set to false,

// then call WriteMinidump. You can also use this technique if you want to
|
||||
// use different minidump callbacks for different call sites.
|
||||
//
|
||||
// In either case, a callback function is called when a minidump is written,
|
||||
// which receives the unqiue id of the minidump. The caller can use this
|
||||
// id to collect and write additional application state, and to launch an
|
||||
// external crash-reporting application.
|
||||
//
|
||||
// It is important that creation and destruction of ExceptionHandler objects
|
||||
// be nested cleanly, when using install_handler = true.
|
||||
// Avoid the following pattern:
|
||||
// ExceptionHandler *e = new ExceptionHandler(...);
|
||||
// ExceptionHandler *f = new ExceptionHandler(...);
|
||||
// delete e;
|
||||
// This will put the exception filter stack into an inconsistent state.
