Parameters:

  • description - User-provided description of what happened before the crash

SetNotes

void SetNotes(const wchar_t* notes);

Description: Sets the initial value of the 'notes' field. BugSplat web application users can edit this field.

Parameters:

  • notes - Additional notes or debugging information

SetAttribute

void SetAttribute(const wchar_t* name, const wchar_t* value);

Description: Sets custom attributes that will be included with crash reports.

Parameters:

  • name - Attribute name

  • value - Attribute value

SetMiniDumpType

void SetMiniDumpType(MINIDUMP_TYPE dumpType);

Description: Configures the type of minidump to generate during crashes.

Parameters:

  • dumpType - Windows MINIDUMP_TYPE enumeration value

SetHangDetectionTimeout

void SetHangDetectionTimeout(int ms);

Description: Sets the timeout used to determine if a process is hung.

Parameters:

  • ms - Timeout in milliseconds (default: 5000). Use 0 to disable hang detection.

Crash Detection & Reporting

GenerateDump

void GenerateDump(LPEXCEPTION_POINTERS const exceptionPointers, 
                  MINIDUMP_TYPE dumpType = MINIDUMP_TYPE::MiniDumpNormal|MINIDUMP_TYPE::MiniDumpFilterTriage) const;

Description: Manually generates a BugSplat crash report with the specified exception information.

Parameters:

  • exceptionPointers - Pointer to exception information structure

  • dumpType - Type of minidump to create (default: MiniDumpNormal|MiniDumpFilterTriage)

CreateXmlReport

void CreateXmlReport(const wchar_t* xmlReport);

Description: Sends an XML report to BugSplat, bypassing minidump creation. Program execution continues normally after this call.

Parameters:

  • xmlReport - XML-formatted report string

Note: See MyConsoleCrasher.cpp for XML schema examples.

CreateAsanReport

void CreateAsanReport(const char* asanReport);

Description: Creates a crash report specifically for AddressSanitizer (ASAN) errors.

Parameters:

  • asanReport - ASAN error report string

File Attachments

AddAttachment

void AddAttachment(const wchar_t* filepath);

Description: Adds a file to be included with crash reports.

Parameters:

  • filepath - Full path to the file to attach

ClearAttachments

void ClearAttachments();

Description: Removes all previously added file attachments.

Crash Management

PostCrash

void PostCrash();

Description: Posts a single crash report and removes the folder after successful upload.

PostAllCrashes

bool PostAllCrashes();

Description: Posts all pending crash reports. This method blocks until completion.

Returns: true if any crashes were posted, false otherwise

Note: Should only be called on a new thread to avoid blocking the main application.

PostAllCrashesAsync

bool PostAllCrashesAsync();

Description: Posts all pending crash reports on a new background thread.

Returns: Always returns true

Utility Methods

IsWerEnabled

bool IsWerEnabled();

Description: Checks if Windows Error Reporting integration is currently enabled.

Returns: true if WER integration is enabled, false otherwise

AllocGuardMemory

void AllocGuardMemory(size_t nbytes);

Description: Allocates guard memory that is freed in the default GlobalExceptionFilter. By default, a three-megabyte guard memory block is created.

Parameters:

  • nbytes - Number of bytes to allocate

FreeGuardMemory

void FreeGuardMemory();

Description: Frees previously allocated guard memory.

GetCrashFolder

const wchar_t* GetCrashFolder();

Description: Returns the folder path where current crash artifacts will be stored.

Returns: Path string in format R:\BugSplat\{unique-guid-string}

SetSuspendingState

void SetSuspendingState(BOOL status);

Description: Sets the suspending state for crash handling.

Parameters:

  • status - Suspension status flag

GetLogFilePath

const wchar_t* GetLogFilePath();

Description: Returns the path to the BugSplat log file.

Returns: Path string to log file

CleanupExceptionSystem

void CleanupExceptionSystem();

Description: Explicitly remove BugSplat's current working folder, log file, and crash state file. This function is needed on Xbox because the system terminates the monitor program and doesn't give it a chance to exit.

Helper Functions

CRT Exception Handling

BugSplat provides helper functions to configure CRT (C Runtime) exception handling for comprehensive crash detection.

SetGlobalCRTExceptionBehavior

inline void SetGlobalCRTExceptionBehavior();

Description: Configures global CRT exception handlers. Should be called once during application initialization.

Configured Handlers:

  • set_terminate() - Handles C++ termination

  • _set_purecall_handler() - Handles pure virtual function calls

  • _set_invalid_parameter_handler() - Handles invalid parameter errors

  • _set_new_handler() - Handles memory allocation failures

SetPerThreadCRTExceptionBehavior

inline void SetPerThreadCRTExceptionBehavior();

Description: Configures per-thread CRT exception handling. It should be called in each thread of your application.

Configured Handlers:

  • Signal handling for SIGABRT

  • Abort behavior configuration

Usage Examples

Basic Initialization

#include "BugSplat.h"

// Initialize BugSplat
BugSplat BugSplat(L"MyDatabase", L"MyApp", L"1.0.0");
    
int main() {
   
    // Configure global CRT exception handling
    SetGlobalCRTExceptionBehavior();
    
    // Configure per-thread CRT exception handling
    SetPerThreadCRTExceptionBehavior();
    
    // Configure BugSplat options
    BugSplat.SetUser(L"john.doe");
    BugSplat.SetEmail(L"[email protected]");
    BugSplat.SetKey(L"main-session");
    
    // Your application code here...
    
    return 0;
}

Notes and Best Practices

  1. Initialization: Always call SetGlobalCRTExceptionBehavior() once during application startup.

  2. Thread Safety: Call SetPerThreadCRTExceptionBehavior() in each thread that should report crashes.

  3. File Attachments: Be mindful of file sizes when adding attachments to avoid large uploads.

  4. Custom Attributes: Use SetAttribute() to add context-specific information that will help with crash analysis.
