Trying to access string in struct causes segmentation fault - c

Question

It's my first time posting a question here and i'll try to be as precise as I can.So i have this project and when i try to access a string in a struct it gives me a segmentation fault.
struct InfoSession {
TabNodePtr FirstTab;
TabNodePtr LastTab;
TabNodePtr CurrTab;
TabNodePtr AuxTab;
char* OpeningAddress;};
this is the struct included in the Session.c file where i have all the functions that i want to call in my main.
void SessionNewOpeningAddress(char * OpeningAddress,InfoSessionPtr Session){
scanf("%s",&OpeningAddress);
strcpy(Session->OpeningAddress,OpeningAddress);}
this is one of the functions that cause a segmentation fault(after testing i realised that each function that calls Session->OpeningAddresscause a segmentation fault.)This is my main.c where my main is included.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "Session.h"
int main(int argc, char *argv[]) {
InfoSessionPtr MySession=NULL;
int option;
char OpeningAddress;
do{
printf("\n\n1. Create Session.\n\
2. Create new tab.\n\
3. Go to next tab.\n\
4. Go to previous tab.\n\
5. Move tab left.\n\
6. Move tab right.\n\
7. Set new opening address.\n\
8. Show the default opening address.\n\
9. Go to next site.\n\
10.Go to previous site.\n\
11.Show the current address.\n\
12.Close the current tab.\n\
13.Close session.\n\
14.Open a new address.\n\
Dwste thn epilogh sas(1-14, 0 gia eksodo):");
scanf("%d",&option);
switch(option)
{case 1:
SessionNew(&OpeningAddress);
MySession =&SessionNew;
printf("The Session has been created!");
break;
case 2:
SessionNewTab(MySession);
break;
case 3:
SessionTabNext(MySession);
break;
case 4:
SessionTabPrev(MySession);
break;
case 5:
SessionTabMoveLeft(MySession);
break;
case 6:
SessionTabMoveRight(MySession);
break;
case 7:
printf("Dwste nea dieuthinsi gia default\n");
SessionNewOpeningAddress(&OpeningAddress,MySession);
break;
case 8:
SessionShowOpeningAddress(MySession);
break;
case 9:
SessionSiteNext(MySession);
break;
case 10:
SessionSitePrev(MySession);
break;
case 11:
SessionAddressShow(MySession);
break;
case 12:
SessionTabClose(MySession);
break;
case 13:
SessionClose(MySession);
break;
case 14:
SessionNewAddress(&OpeningAddress,MySession);
break;
}
}while(option);
return 0;}
I've searched all over the internet but i still cant understand where the problem is.Anyone that can help me please reply as fast as you can.
Oh and the SessionNew function is here(everything works fine in this function):
InfoSessionPtr SessionNew(char * OpeningAddress){
TabNodePtr Tab;
InfoSessionPtr IS;
SiteNodePtr Site;
IS=malloc(sizeof(struct InfoSession));
Tab=malloc(sizeof(struct TabNode));
Site=malloc(sizeof(struct SiteNode));
IS->OpeningAddress=malloc(strlen(OpeningAddress)+1);
Site->Address=malloc(strlen(OpeningAddress)+1);
IS->AuxTab = NULL;
IS->CurrTab = Tab;
IS->FirstTab = Tab;
IS->LastTab = Tab;
Tab->NextTab = Tab;
Tab->PrevTab = Tab;
Site->UpTab = Tab;
Tab->CurrSite = Site;
Tab->FirstSite = Site;
OpeningAddress = "google";
strcpy(IS->OpeningAddress,OpeningAddress);
strcpy(Site->Address,IS->OpeningAddress);}

Answer 1

Consider this. I moved the statement OpeningAddress = "google"; before the malloc and changed it to strcpy. As I did nt have the session.h file and the other functions, i removed those references.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct InfoSession {
char* OpeningAddress;};
typedef struct InfoSession *InfoSessionPtr;
void SessionNewOpeningAddress(char * OpeningAddress,InfoSessionPtr Session){
scanf("%39s",OpeningAddress);
strcpy(Session->OpeningAddress,OpeningAddress);}
InfoSessionPtr SessionNew(char * OpeningAddress){
InfoSessionPtr IS;
IS=malloc(sizeof(struct InfoSession));
strcpy ( OpeningAddress, "google");
IS->OpeningAddress=malloc(strlen(OpeningAddress)+1);
strcpy(IS->OpeningAddress,OpeningAddress);
return IS;}
int main(int argc, char *argv[]) {
InfoSessionPtr MySession=NULL;
int option;
char OpeningAddress[40] = "g";
do{
printf("\n\n1. Create Session.\n\
2. Create new tab.\n\
3. Go to next tab.\n\
4. Go to previous tab.\n\
5. Move tab left.\n\
6. Move tab right.\n\
7. Set new opening address.\n\
8. Show the default opening address.\n\
9. Go to next site.\n\
10.Go to previous site.\n\
11.Show the current address.\n\
12.Close the current tab.\n\
13.Close session.\n\
14.Open a new address.\n\
