Visual C++ "Undeclared identifier" error on sprintf only in destructor

Question

I have a program were I am trying to do some simple text logging to find an error that only manifests in release mode. I have added my logging code, and it is not flagged as an error anywhere except in the class's destructor:

CParameterMgr::~CParameterMgr ()
{
   sprintf(logData, "Deleting m_pValueBuff (Destructor)");
   TextLogger::WriteLog(logData);

   delete [] m_pValueBuff;
}

I am actually getting "error C2065: 'sprintf' : undeclared identifier"

Can anyone explain why sprintf cannot be used in a destructor?

Thanks

Answer 1

No limitation on usage of sprintf in destructor exists. You just forgot include appropriate header file.

C-style way is

#include <stdio.h>

C++-style way is

#include <cstdio>
