Qt Safe Monitor C API
This document lists the public C functions declared under src/monitor/inc. Types like quint32, qint32, and qchar are defined in QtSafeRenderer/qsafeglobal.h. Unless otherwise noted, pointers must be non-null and buffers must be large enough to hold the written data.
Using Monitor
You can use Qt Safe Monitor in two ways, depending on where the actual display CRC is read and how verification is triggered:
- Standalone solution (monitor-integrated CRC read): The Qt Safe Monitor process integrates the OutputVerifierAdaptation into the Qt Safe Monitor library and reads the actual CRC directly from the hardware. This approach is used with Qt Quick and Qt Quick Ultralite. In this scenario, use the APIs provided by <qsrmonitor.h>.
- Dual-process solution (renderer-reported CRC): The Qt Safe Renderer process reads the actual CRC and reports it to the Qt Safe Monitor process. In this scenario, use the event-based APIs from <eventProcessor.h> together with the message definitions in <message.h>.
