KSCrash is implemented as a layered architecture. Each layer can in theory be compiled without the layers adjacent or above.

This top level layer provides a "clean" interface to the crash system. It is expected that the API at this level will be largely idiomatic to the backend system it will be communicating with.

Primary entry points: KSCrashInstallation.h, KSCrashInstallationXYZ.h

Handles high level configuration and installation of the crash recording and crash reporting systems.

Primary entry point: KSCrash.h

Provides storage and retrieval of crash reports and other configuration data. Also provides file paths for more primitive access by other layers.

Primary entry point: KSCrashReportStore.h

Records a single crash event. This layer is implemented in async-safe C.

Primary entry point: KSCrashC.h

Processes, transforms, and sends reports to a remote system.

Primary entry point: KSCrash.h

Traps application errors and passes control to a supplied function. It handles the following errors:

• Mach Exception
• Signal
• NSException
• Main Thread Deadlock

Primary entry point: KSCrashMonitor.h

Low level interface for transforming, processing, and sending crash reports.

Primary entry points: KSCrashReportFilter.h, KSCrashReportFilterXYZ.h
