questions on reading in a file (detailed)

Posted by Matthew Kaoru Hallberg on 1999-10-28

Hi. 
It's me again, and yet another question for all of you. 
I solved my struct problem, thanks for the help but now I have a new 
question.... (still for visual c++ 6.0)
is it possible to read in more than one line at a time using sscanf? 
suppose I have a data file that has contents like this: 
          
F0000000: FF043000 FF043000 00000000 00000000 
F0000010: 7F000000 7F000000 FF070000 FF070000 
F0000020: 00000000 00000000 A0070000 A0070000

and I want to read in the first occurence of register 8 
go to the next line, and read in the occurence of reg 10 
like this (don't care about anything else... just those two values): 
                 register10                 register 8
F0000000: FF043000 FF043000 00000000 00000000 
                                               ^^^^^^^^^^^ 1st read
F0000010: 7F000000 7F000000 FF070000 FF070000 
                ^^^^^^^^^^^ 2nd read 
F0000020: 00000000 00000000 A0070000 A0070000 
//you get the point?.... 
and store them into the variables: RegFuncData.HiAddr, and RegFuncData.LoAddr 
this is what I had prior to finding out I needed to skip the initial register 
10 column 

while(ar.ReadString(strOneLine))
{
       sscanf(strOneLine,"(somehow skip ahead 11 spaces) 8%u (somehow skip
     ahead 10 spaces) ", &RegFuncData.LoAddr, &RegFuncData.HiAddr); 
       // adds the data to the array 
       m_RegisterArray.Add(RegFuncData);
}

Can anyone help me out with the indicated problems? 
I am using visual C++ 6.0, thanks a bunch...
