[reactos] 08/08: [NTVDM] Create the CMOS ram file in NTVDM's own directory, instead of in whatever current directory we are running.

This fixes the age-long annoyance that wherever you ran a DOS program with NTVDM, its cmos.ram file would be created in the same current directory the DOS program was being started. This created at least two problems: - useless pollution of directories with cmos.ram files; - for installers, e.g. of Turbo C 1.x that enumerate the install files from their directories to be copied/extracted somewhere, the cmos.ram file could then be enumerated along and cause the installation to interrupt and/or fail. Now the cmos.ram file is created in the same directory NTVDM resides (usually in System32...). Also, debug-print out only loading errors instead of successes as well. --- subsystems/mvdm/ntvdm/hardware/cmos.c | 121 ++++++++++++++++++++++++---------- subsystems/mvdm/ntvdm/ntvdm.h | 5 ++ 2 files changed, 93 insertions(+), 33 deletions(-) diff --git a/subsystems/mvdm/ntvdm/hardware/cmos.c b/subsystems/mvdm/ntvdm/hardware/cmos.c index 8482553c08e..60abb6ffef9 100644 --- a/subsystems/mvdm/ntvdm/hardware/cmos.c +++ b/subsystems/mvdm/ntvdm/hardware/cmos.c @@ -22,6 +22,8 @@ /* PRIVATE VARIABLES **********************************************************/ +#define CMOS_RAM_FILE "cmos.ram" + static HANDLE hCmosRam = INVALID_HANDLE_VALUE; static CMOS_MEMORY CmosMemory; @@ -438,41 +440,88 @@ BOOLEAN IsNmiEnabled(VOID) return NmiEnabled; } +static inline BOOL +CmosWriteFile( + _In_ HANDLE FileHandle, + _In_ PVOID Buffer, + _In_ ULONG BufferSize, + _Out_opt_ PULONG BytesWritten) +{ + BOOL Success; + ULONG Written; + + SetFilePointer(FileHandle, 0, NULL, FILE_BEGIN); + Success = WriteFile(FileHandle, Buffer, BufferSize, &Written, NULL); + if (BytesWritten) + *BytesWritten = (Success ?
