示例1: PrescanMacroArg
// Macro-expand a macro argument 'arg' to create 'expandedArg'.
// Does not replace 'arg'.
// Returns nullptr if no expanded argument is created.
TPpContext::TokenStream* TPpContext::PrescanMacroArg(TokenStream& arg, TPpToken* ppToken, bool newLineOkay)
{
// expand the argument
TokenStream* expandedArg = new TokenStream;
pushInput(new tMarkerInput(this));
pushTokenStreamInput(arg);
int token;
while ((token = scanToken(ppToken)) != tMarkerInput::marker && token != EndOfInput) {
