I'm looking at
http://bitbucket.org/tortoisehg/crew/src/e214839bf369/win32/shellext/ContextMenu.cpp#cl-445
we have
STDMETHODIMP
CShellExt::GetCommandString(
UINT_PTR idCmd, UINT uFlags, UINT FAR *reserved,
LPSTR pszName, UINT cchMax)
{
*pszName = 0;
char *psz;
TDEBUG_TRACE(
"CShellExt::GetCommandString: idCmd = " << idCmd
<< ", uFlags = " << uFlags
);
MenuIdCmdMap::iterator iter = MenuIdMap.find(static_cast<UINT>(idCmd));
if (iter != MenuIdMap.end())
{
TDEBUG_TRACE(
"CShellExt::GetCommandString: name = " << iter->second.name);
psz = (char*)iter->second.helpText.c_str();
}
else
{
TDEBUG_TRACE(
"CShellExt::GetCommandString: can't find idCmd " << idCmd);
psz = "";
}
if (uFlags & GCS_UNICODE)
{
wcscpy((wchar_t*)pszName, _WCSTR(psz));
}
else
{
strcpy((char*)pszName, psz);
}
return NOERROR;
}
Can someone explain what _WCSTR() does?
http://msdn.microsoft.com/en-us/library/bb776083(VS.85).aspx specifies
that if uFlags & GCS_UNICODE, a "unicode" string must be copied into
pszName (I assume a wstring is meant with that).
But how do we get that wstring?

Usage of _WCTSR() seems to go back to
