Does anybody know what are the names of the Win32 system calls for direct
reading and writing of disk sectors, rather than the NTFS routines?

Look at the following sample, I am not sure whether this is what you
want.

Do you mean write file into hard drive with a file name?
Look at the following sample, I am not sure whether this is what you
want.
HANDLE hFile;
DWORD wmWritten;
char strData[] = "Test data written to explain the win32 file sample";
hFile = CreateFile("C:\\test.txt",GENERIC_READ|GENERIC_WRITE,
FILE_SHARE_READ,NULL,OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);
WriteFile(hFile,strData,(DWORD)(sizeof(strData)),&wmWritten,NULL);
CloseHandle(hFile);

it's off-topic on comp.lang.c as it necessiates the use of non-
standard
extensions to the C language.

I suspect they didn't bother, because the bridge is going to be closedRobert said:Any such worries are moot, because the end of world is already
scheduled for Thursday night or Friday morning. If you don't
believe me, in the San Francisco bay area, tune to channel 11-2 (on
RF channel 12-2), where the NBC Weather channel shows the five-day
forecast ending Thursday. There won't be any Friday or Saturday
etc. The world will already have ended then.
P.S. Does anybody know the *real* reason why the NBC Weather
channel is showing that weirdness? Did everyone at NOAA go on
strike four days ago, so there are no updated 5-day forecasts since
then, and NBC is simply showing the last info they had before the
strike, which now is the one remaining day from the very old 5-day
forecast they had before the strike?
By the way, yesterday it showed only two days, Wed and Thu, with
three blank spots, so at least it's consistent in showing EOW Thu/Fri.

A month or two ago There was a 96% chance of a major earth quake in
the San Francisco bay area, on the following Friday.

I see no language extensions here. Library functions beyond those in the
standard library are a different matter.
Most C programs use external libraries;
yes
that doesn't make them "not C".
However, I'd agree that this is off-topic here (meaining comp.lang.c),
yes
as it's *solely* about a particular OS API

C is defined by the standard. But where in the standard are thes
undefined things are defined? None of my compilesers can find them
HANDLE
DWORD
hFile
CreateFile
WriteFile
CloseFile
All these are clearly not C. They may be used in some properitary
extensions
but nowhere in C nor in any documentation related to my OS
is one of them defined, so clearly that all is not C.
Nobody said:User-defined types and functions are not "extensions".
Not so.
C programs which use functions and types beyond those defined by the
standard are still C programs.
Maybe you are mistaking this group for comp.std.c?
