Functions

func EnumDisplayMonitors

func EnumDisplayMonitors(t *testing.T)

func MonitorEnumProcCallback

func MonitorEnumProcCallback(hMonitor C.uintptr_t, hDC C.uintptr_t, lpRect C.uintptr_t, dwData C.uintptr_t) C.bool

MonitorEnumProcCallback is our callback function which will be called from the DLL. Cgo note: Using //export in a file places a restriction on the preamble: since it is copied into two different C output files, it must not contain any definitions, only declarations. If a file contains both definitions and declarations, then the two output files will produce duplicate symbols and the linker will fail. To avoid this, definitions must be placed in preambles in other files, or in C source files.

func SetProcessDpiAwareness

func SetProcessDpiAwareness() bool

SetProcessDpiAwareness enables per-monitor DPI awareness V2. If successful, returns true; otherwise returns false. References: - https://stackoverflow.com/a/43537991 - https://github.com/anaisbetts/PerMonitorDpi/blob/63570f78d9a3ff032bcd0d8a50169af1a57c2090/SafeNativeMethods.cs
