Hi,
For the second part of my code (Part 1 is titled Linked List and Array of POinters) I need to fill in the Linked List with values for the line_used from a file. The file has the following format:
Array size: 17 x 17 logic blocks.
Routing:
Net 0 (i_63_)
SOURCE (18,1) Pad: 0
OPIN (18,1) Pad: 0
CHANY (17,1) Track: 2
CHANX (17,1) Track: 3
IPIN (17,1) Pin: 2
SINK (17,1) Class: 0
CHANX (17,1) Track: 2
CHANY (16,2) Track: 4
IPIN (16,2) Pin: 3
SINK (16,2) Class: 0
Hence I need to read the Channel X or Y and the coordinates and the corresponding track number. Depending on the Channel (X or Y ) and the coordinates I have to fill up the linked list.
The logic is illlustrated in my code but when I run the program on VC++ I get an error message that the exe file has encountered an error. When I try to debug it says that it cannot evaluate the line_used expression and the temp=temp->nextptr expression.
Also further I get the following errors on debugging

The thread 0x7E8 has exited with code 0 (0x0).
The thread 0xF88 has exited with code -1073741819 (0xC0000005).
On GCC I simply get a Segmentation Fault.
I am again all confused where to try looking for tthe problem.
I tried printing out the tracknumber and coordinates also. They do print if I comment the part from **HERE** to **HERE**
I am attaching the code below:
Code:#include<stdio.h> #include<stdlib.h.> struct switch_matrix { int pin_no; int line_used; struct switch_matrix *nextptr; }; struct switch_block { struct switch_matrix *Array[40]; }Layout[18][18]; typedef struct switch_matrix SWITCH; void build_univ_switch (struct switch_block *X); int main() { int x1=0,x2=0,y1=0,y2=0,trackno1=0,trackno2=0,m,n; FILE *fp; SWITCH *temp; char ch; fp=fopen("e64.r","r"); while(!feof(fp)) { **HERE** if (x1==x2) { if (y1==y2) { temp=Layout[17-y1][x1].Array[19+trackno2]; temp=temp->nextptr; temp->line_used=1; temp=Layout[17-y1][x1].Array[19-trackno1]; temp=temp->nextptr; temp=temp->nextptr; temp->line_used=1; } else { if (y2==y1+1) { temp=Layout[17-y1][x1].Array[19-trackno1]; temp->line_used=1; temp=Layout[17-y1][x1].Array[9-trackno2]; temp=temp->nextptr; temp->line_used=1; } else { if (y2 > y1+1) { temp=Layout[17-(y2-1)][x1].Array[19+trackno2]; temp->line_used=1; temp=Layout[17-(y2-1)][x1].Array[9-trackno2]; temp=temp->nextptr; temp=temp->nextptr; temp->line_used=1; } } } } else { if (y1==y2) { if (x1==x2+1) { temp=Layout[17-y2][x2].Array[19+trackno2]; temp=temp->nextptr; temp=temp->nextptr; temp=temp->nextptr; temp->line_used=1; temp=Layout[17-y2][x2].Array[29+trackno1]; temp=temp->nextptr; temp=temp->nextptr; temp->line_used=1; } else { if (x1 > x2+1) { temp=Layout[17-y1][x1-1].Array[19-trackno1]; temp=temp->nextptr; temp=temp->nextptr; temp=temp->nextptr; temp->line_used=1; temp=Layout[17-y1][x1-1].Array[29+trackno1]; temp=temp->nextptr; temp->line_used=1; } } } else { if (y2==y1+1) { temp=Layout[17-y1][x2].Array[9-trackno2]; temp=temp->nextptr; temp=temp->nextptr; temp=temp->nextptr; temp->line_used=1; temp=Layout[17-y1][x2].Array[29+trackno1]; temp->line_used=1; } } } **HERE** ch=fgetc(fp); if (ch=='S') { x1 = 0; y1 = 0; x2 = 0; y2 = 0; ch=fgetc(fp); if(ch=='C') { ch=fgetc(fp); if(ch=='H') { ch=fgetc(fp); if(ch=='A') { ch=fgetc(fp); if(ch=='N') { ch=fgetc(fp); if(ch=='X') { ch=fgetc(fp);//the blank //ch=fgetc(fp);//the colon ch=fgetc(fp);//the ( fscanf(fp,"%d",&x1); printf("%d\n",x1); ch=fgetc(fp);//the , fscanf(fp,"%d",&y1); printf("%d\n",y1); for(m=0;m<10;m++)//no of charac till u reach track no ch=fgetc(fp); fscanf(fp,"%d",&trackno1); printf("go\n"); printf("%d\n",trackno1); //store these in the linked list } else if (ch=='Y') { ch=fgetc(fp);//the blank //ch=fgetc(fp);//the colon ch=fgetc(fp);//the ( fscanf(fp,"%d",&x2); printf("%d\n",x2); ch=fgetc(fp);//the , fscanf(fp,"%d",&y2); printf("%d\n",y2); for(n=0;n<10;n++)//no of charac till u reach track no ch=fgetc(fp); fscanf(fp,"%d",&trackno2); printf("%d\n",trackno2); //store these in the linked list } } } } } } } fclose(fp); return 0; } void build_univ_switch(struct switch_block *X) { SWITCH *head; SWITCH *currentptr; int i, j; for (i = 0; i<40; i++) { /*BUILDS LINKED LIST*/ head = NULL; for (j = 1; j<=4; j++) { currentptr = (SWITCH *) malloc (sizeof (SWITCH)); currentptr->line_used = 0; currentptr->nextptr = head; head = currentptr; } //currentptr = head; X->Array[i] = head; } }
I am open to any help as I can get regarding this.
