Re: When were scanf_s functions introduced?

The DLL version required to support security-enhanced fucntions is
MSVCR80.dll which is 612 kb in size.

I relinked statically (/MT) which statically links in libcmt.lib (about 7.4 Mb).
However the resultant apps (which are not very big) amount to
about 100 kb ; e.g. this file hasher utility
http://www.jensign.com/hash/index.html

I don't have a good understanding of how static linking works with obj .dll
libraries but I gather it just extracts the code from the static CRT library that
is referenced in the application (hence my resultant code is still small ) ?

Thanks,

I would just redistribute the DLL version of the CRT. VC2005 comes with a prepackaged installer and merge modules for
it, I believe.

Thanks. So I guess I need to recompile with /MT to static
link code into my application to ensure backward compatiblity.

Yes unless somebody else has already installed MSVCR80.dll.

(a bit rusty on VC++ here ..)
I was looking at my compile options in VS 2005 and the /MD switch
is used for release by default. Does this mean that if I compile my
C code in VS 2005 with the default /MD compile switch, and specify
scanf_s() functions, the target platform will need updated dll (MSVCR80.dll)
with those functions since the CRT is not statically linked into my application?

They ship with the VS2005 CRT (and probably later CRTs). They were not present in the VS2003 (or earlier) CRTs.

When were the security-enhanced functions, like scanf_s, sscanf_s etc. introduced?
I noticed that they are not included in the PSDK April 2005 MSDN documentation,
but are included in VS 2005 docs.
