Thread: struct passing

Im using an ansi c gcc comiler and im trying to pass a structure variable from a seperate file into the main.c file and when i do i get the errors unidefied symbol 'ts" warning argument 1 is incompatiable with prototype what am i doing wrong?

Code:

int commandLineArguments(int, char**);
int MainMenu(int*);

int main(int argc, char** argv)
{
   int x = 10;

   TennisStoreType ts;
   commandLineArguments(argc, argv);
   MainMenu(&x);

   return EXIT_SUCCESS;
}

int commandLineArguments(int argc, char **argv) 
{   
    /* makes a local copy of argc and **argv */

 
   FILE *customer, *stock, *logfile; 
   
    /* declares a pointer to each file*/

    /* test if 4 arguments exist including the exucutable*/

   if(argc !=4) 
   {
     printf("please enter 3 cmd arguments!\n");
     return 1;  
     /* stop pocessing*/
   }

    /* attempt to open and read arg 1*/

   customer = fopen(argv[1], "r");

    /* check if custome.csv exists*/

   if(customer ==NULL)
   {
     printf("cannot open %s for reading\n", argv[1]);
     return 1;  
     /* can't go on*/
   }

     /* try to open stock.csv and read it*/

   stock = fopen(argv[2], "r");
  
     /* if stock.csv does not exist error*/
   
   if(stock == NULL)
   {
     printf("cannot open %s for reading\n",argv[2]);
     return 1;  

     /* stop processing*/
   }

     /* open logfile for reading */  
 
   logfile = fopen(argv[3], "r");

     /* check if logfile exists*/

   if(logfile == NULL)
   {
     printf("cannot open %s for reading\n", argv[3]);
     return 1;  
 
     /* stop processing*/
   }
   
     /* close all files */

   fclose(customer);
   fclose(stock);
   fclose(logfile);

   return 0;

    
}

int MainMenu(int *a)
{

  int choice = 0;

  /* declare variables*/
  
  /* keep doing this until its not equal to 9*/
 
  do
   {

     printf("\n\t*****Main Menu:\t*****\n");
     printf("1) Add Customer\n");
     printf("2) Add Stock\n");
     printf("3) Delete Record\n");
     printf("4) Display Customer\n");
     printf("5) Display stock\n");
     printf("6) Make Sale\n");
     printf("7) Sales Log\n");
     printf("8) Save and Exit\n");
     printf("9) Abort\n");
   
     printf("Select Your option (1-9):\n");

     fscanf(stdin, "%d",&choice);
     
     /* User Input */
   
     readRestOfLine(); 
     
     /* flushes the stdin buffer for better input*/

     /* switch statement to select function*/

     switch(choice)
     {
       case 1:
       printf("Add stock");

       addCustomer(&ts);
      /* i want to pass it into addCustomer somehow*/

       break;

     }

  }
  while(choice !=9);

  /* end of do while */  

  /* switch case */

  /*  do while

  /* while !=10 */  

  return 0;
}


/* then in the second file which contains all the menu option functions such as addCustomer*/

void addCustomer(TennisStoreType* ts)
{

     printf("It better call this function!");
}

ts is declared in main, thus it is only visible in main. It is not visible to the compiler in your other functions. You need to pass a pointer to the ts struct to MainMenu first.

could you give me an example sorry for the bother im having allot of trouble passing variables
