Please example of RtlStringCbVPrintfA...!

Hi.
I try to use RtlStringCbVPrintfA funciton.

my code:
RtlStringCbVPrintfA(pszBUFF, nPathSize, "%s\\%s", szVolume, szFolder);

But the code is 'too many parameter'.
So I made next code:
void printfA(PCHAR szDest, int nDestSize, PCHAR Format, ...)
{
va_list va;
NTSTATUS status;

va_start(va, Format);
status = RtlStringCbVPrintfA(szDest, nDestSize, Format, va);
va_end(va);
}


But the code doesn't work also.

How do I use the function?

Hi,

Maybe you will be interested in this article

<quote> Some important advice as you get started: read the documentation.
Many application developers approach a new technology by going directly to
the samples and then straight into writing code. Opinions vary on the
effectiveness of this approach for applications. When it comes to drivers,
though, thereâ??s no disagreement: spend some time with the documentation and
get a good solid understanding of how drivers work before you even think
about trying to implement one. </quote>

Good luck,

Of course, as the documentation shows. In this example, you want
RtlStringCbPrintfA without the V.

What are you going to do with this? There are few cases in the DDK where
you need an ANSI string.
