cutting a list into sub list then

[erwiali]

Please! i need help on this . it suppose to cut the original linklist of head hp such that the sumM <=m and sumV <=v . this is part of a program that reads an input file of itemsets where each item has cod volume mass . then you key the max volume and max mass for a container . the program has to know how much containers are needed . and stor in each container some items. i did read the file to linkedlist ,and i made an array of pointers each index suppose to point to the items within a store .

 /* Create an array of pointer of type item_t of size N where each index points to
            set of items in a container .*/

         dmat=(item_t **)malloc(*Np*sizeof (item_t *));
             if(dmat==NULL){
                 printf("Memory Allocation Error.\n");
                 exit(EXIT_FAILURE);
                 }
               temp=hp;
               for(i=0;i<*Np;i++){
                    sumM=0;
                    sumV=0;
                    p=temp;
                    V=temp;
                for(;temp!=NULL && (sumM+=temp->mass)<m &&(sumV+=temp->volume)<v;temp=temp->next)
                             V=V->next;
                       V=NULL;
                       dmat[i]=p;
                       for(p=dmat[i];p!=NULL;p=p->next)
                           printf(":%s %d %d\t",p->code,p->volume,p->mass);
                           printf("\n\n");
                   }

       return dmat;
    }
