宏函数未按预期扩展

编辑可能的重复链接无助于解决问题。

Bellow 是一个带有注释的最小可编译代码，问题是ERR_INFO宏会导致宏函数LOG_IF_FAILED扩展HRESULT参数的麻烦

我确定这个问题是微不足道的，但调试宏是一场噩梦。

#define UNICODE
#include <Windows.h>
#include <comdef.h>
#include <iostream>
#include <cwchar>

void DebugLogTrace(PCTSTR format_string, ...)
{
// implementation not important
}
// Writes a sprintf-formatted string to the logging file.
#define TRACE(...) DebugLogTrace(__VA_ARGS__)
#ifdef UNICODE
// Show only file name instead of full path wide version
#define FILENAME (std::wcsrchr(TEXT(__FILE__), L'') ? std::wcsrchr(TEXT(__FILE__), L'') + 1 : TEXT(__FILE__))
// Wide string function name
#define FUNCNAME __FUNCTIONW__
// boilerplate macro
#define ERR_INFO FILENAME, FUNCNAME, __LINE__
// Log HRESULTs if failed.
#define LOG_IF_FAILED(file_name, func_name, line, hr) if (FAILED(hr)) 
{ TRACE(TEXT("%s %s %i %s"), file_name, func_name, line, _com_error(hr).ErrorMessage()); }
#else
// ANSI versions here ...
#endif // UNICODE
int main()
{
HRESULT hr = CoInitializeEx(nullptr,
COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE);
// Here hr is not inserted into expansion
// ERR_INFO macro is causing problems somehow
LOG_IF_FAILED(ERR_INFO, hr);
// This works however
LOG_IF_FAILED(FILENAME, FUNCNAME, __LINE__, hr);
return 0;
}
