RM_PROCESS_INFO::TSSessionId is unsigned but RM_INVALID_TS_SESSION is signed

[KalleOlaviNiemitalo]

RM_INVALID_TS_SESSION is intended to be compared to RM_PROCESS_INFO::TSSessionId but they have different types; one is signed and the other is unsigned. That then requires an unchecked cast when these are compared in C#.

win32metadata/generation/WinSDK/RecompiledIdlHeaders/um/RestartManager.h

Lines 31 to 32 in c2b7ea9

	// Uninitialized value for TS Session ID
	#define RM_INVALID_TS_SESSION -1

win32metadata/generation/WinSDK/RecompiledIdlHeaders/um/RestartManager.h

Lines 99 to 100 in c2b7ea9

	DWORD TSSessionId; // Terminal Service session ID of
	// process (-1 if n/a)

Can the same type be used for both? I guess it would have to be the unsigned type, for consistency with WTS_CURRENT_SESSION, WTSQuerySessionInformationW, and others.

Similar considerations may apply to RM_INVALID_PROCESS vs. RM_UNIQUE_PROCESS::dwProcessId, but I haven't found any formal documentation on the intended use of RM_INVALID_PROCESS.

win32metadata/generation/WinSDK/RecompiledIdlHeaders/um/RestartManager.h

Lines 33 to 34 in c2b7ea9

	// Uninitialized value for Process ID
	#define RM_INVALID_PROCESS -1

win32metadata/generation/WinSDK/RecompiledIdlHeaders/um/RestartManager.h

Line 88 in c2b7ea9

DWORD dwProcessId; // PID

I wouldn't change the type of the struct fields. Should the constant values be changed to reflect any implicit conversions that C is doing?
