warning #2228: Unable to expand function 'StringCbPrintfW' inline.

[Snowman]

Hello forum. I am using Pelles C version 8.00.60.
I am compiling the code below with speed optimizations and Level 2 warnings.

Code: [Select]

#define UNICODE
#define _UNICODE

#include <windows.h>
#include <tchar.h>
#include <strsafe.h>

int _tmain(void)
{
    TCHAR test[200];

    (void)StringCbPrintf(test, sizeof test, _T("Hello Windows API!"));
    return 0;
}

The warning in this thread's title is given if I use StringCbPrintf() but not if I use _sntprintf():

Code: [Select]

main.c(14): warning #2228: Unable to expand function 'StringCbPrintfW' inline.
My questions are:

• What can I do about this warning other than disable it?
• Should I use _sntprintf() instead, just for the sake of being inlined?
• Will this be fixed in future versions of Pelles C?

• Do nothing. This warning is only informative that the compiler is unable to inline the function. The function StringCbPrintfW is declared __inline, that is a suggestion to compiler and not an imposition to inline it (like could be __forceinline).
• _sntprintf is not implemented in PellesC. Using it you'll get only an error message suggesting you to use StringCbPrintf()
• There is not so much to fix here. Maybe a better code generator in future versions will do it...

You can simply change the warning level to 1 and see if this will 'hide' that warning.

You can simply change the warning level to 1 and see if this will 'hide' that warning.

Better:

Code: [Select]

#pragma warn(disable:2228)
#include <strsafe.h>
