QuestionHelp with STL list::insert Pin
ForNow21-Sep-22 1:54

Hi

I need a little guidance trying to insert a element my element is a structure here below are my data structures

so I define a structure of type tcbholder struct tcbholder tcbx;

I initialize the iterator member with the following code

C++
tcbx.straverse = tcbx.strptr.begin(); // storage discriptor pointer
	tcbx.stdecsx.blktraverse = tcbx.stdecsx.ablkptr.begin(); // begin block pointer



then to insert a blkdesc type I use the following code

C++
tcbx.stdecsx.ablkptr.insert(tcbx.stdecsx.blktraverse,tcbx.stdecsx.ablkdescx);


I then think I would have to bump up the postion of the iterator so I do the following

C++
tcbx.stdecsx.blktraverse++;


after which I get an exception that I went past the end

Any help would be appreciated

thanks

My first question is am I correct that in initalizing the iterator the code is call list::begin

and then to bump up the interator to get next postion its operator ++


C++
struct blkdesc
   {
       char type;
       int blkaddr;
       int blklen;
       //  struct blkdesc* nextblkdesc;
   };
   struct stdecs
   {
       struct vsmdesc stordesc;
       char* tcb;
       struct blkdesc ablkdescx;
       struct blkdesc fblkdescx;
       //  struct stdecs* nextdecs;

       list<blkdesc> ablkptr;
       list<blkdesc>::iterator blktraverse;
       list<blkdesc> fblkptr;
   };

   struct tcbholder
   {
       char* tcb;
       char programname[8];
       //  struct stdecs *storageptr;
       struct stdecs stdecsx;
       list <stdecs> strptr;
       list <stdecs>::iterator stfirstptr;
       list <stdecs>::iterator straverse;
   };
