Does Printf (et al.) have a size_t size spec?

[vefatica]

Does Printf (and friends) have a size specification that's 32 bits on x86 and 64 bits on x64?

Thanks.

If you don't understand the question, I doubt you would understand an answer to your question.

Use %q or %X, and cast your argument to unsigned __int64 ?

Charles, can you explain further? %X in the HEX type and I'd expect a prefix with it. What's %q?

According to TakeCommand.h, %q is a 64-bit integer and %X is a 64-bit hex integer in Printf(), Qprintf(), and ColorPrintf().

OK, now I see the notes in TakeCmd.h. Hmmm! I've never used %q. And I have always used %X as in C/Win32 ... uppercase hex, with a prefix (usually l or I64) and never casting the matching argument.

That's why I asked, what you want to achieve. Because your question strikes prominently as an XY problem to me.

A related and more specific question:

Suppose I have a HANDLE h (void*, 32 or 64 bits) and I want to do this

Sprintf(szExpr, L"%%@FILECLOSE[<type>]", (cast?) h);
ExpandVariables(szExpr, 0);

Does Sprintf() know about the q type? Can I

Sprintf(szExpr, L"%%@FILECLOSE[%q]", (ULONGLONG) h);

Sprintf and Printf share the same formatting routine, so anything that Printf can do, Sprintf can do.

They also support I64 and I64x.
