Re: [Cpp-Programming] Read position issue within an IOSTREAM class

I couldn't copy the error. I believe that the problem is due to an error in the way I implemented the code.  In the compiler, the cached information is copied to a temporary instance of a class acting as a wrapper to the iostream class.  Then this instance is pushed onto the previous instance of the class as a cross pointer.  The following is the code I use to perform this function:

----------------------

void CSource_Attach (CSource* I)
{
 I->PrevC=CurIn;
 CurIn=I;
}

----------------------

CSource is the wrapper class; I is the instance to push, and PrevC is a member pointer to the previous instance of the class.  Am I doing something wrong?

 

BTW, I tokenize the keywords and types upon reading, but the writing of these appears to work.

As one person said, comparing c++ to c is like comparing Dutch to German... well he said French to English.

Subject: [Cpp-Programming] Read position issue within an IOSTREAM class

 

I need to fill an IOSTREAM class with a part of a file during the process of compiling a C program using multiple passes in a compiler written in C++.  I fill the new instance of an input stream with a part of a file.  This stream stores and processes the auto variables defined within a function.  My plan is to read the part of a function until the first executable statement.  It seems to that.  However, during the declaration phase, nothing is declared.  I'm wondering if maybe I need to explicitly set the read pointer to the beginning of the buffer.  Is this true?  If so, how do I reset the pointer?  I'm sorry about the newbie question, but I don't have available C++ documentation. --
