Passing an array to a function

I am having trouble passing an array to a function, here is my code.

Code:

void get_fields(char *fld1);

Code:

int main(void)
   char array[100];

	get_fields(array);

function code

Code:

/*****************************************************************/

/* get_fields.c-- read sequential text file            */
/*             -- file has newline delimited "records" */
/*             -- records have tab delimited "fields"  */
/* a C Beginner's program:                             */
/* IF THE COMMENTS ARE WRONG PLEASE CORRECT THEM!      */
/* This is meant to be a learning/teaching program.    */
/* This program sacrifices elegance for readability    */
/* If suitable, this may be added to the C course.     */

void get_fields(char *fld1)
{
  char record[100];                 /* array to hold each "record" */ 
       //*fld1, *fld2, *fld3, *fld4;         /* pointers to "fields" */
  FILE *fin;                              /* pointer to input file */
  fin = fopen(FILENAME, "r");             /* open the file to read */
                                                 /* print a header */
  printf("%-25s %-20s %-15s %-15s\n",           
         "Field 1\\t", "Field 2\\t", "Field 3\\t", "Field 4\\n");

  /* the while loop is used to read in the file that fin points to */
  /* use fgets() to read the file. fgets() reads up to a newline   */
  /* fgets() includes the newline in the string it reads and tacks */
  /* a '\0' onto the end of the string. It should be familiar.     */
  while (fgets(record, sizeof(record), fin))
  {
    /* strtok() will be looking for a newline at the end of record */
    if (record[strlen(record) - 1] != '\n')
      /* make sure the newline is there */
      record[strlen(record) - 1] = '\n';
 
    /* use strtok() to get each "field". strtok()'s usage is:      */
    /* char *ptr = strtok(char *s1, const char *s2);               */
    /* the first call of strtok() searches the string s1 for the   */
    /* `token' s2. If found, it replaces the token with '\0' and   */
    /* sets a pointer to the next character                        */
    fld1 = strtok(record, "\t");
    /* after that each call has a NULL pointer as the 1st argument */
    /* & starts searching for another token from the saved pointer */
    /* if strtok() can't find the token, it returns a null pointer */
    /* strtok() is a tricky function to use. 8^D                   */
    //fld1+20 = strtok(NULL, "\t");
    //fld3 = strtok(NULL, "\t");
    //fld4 = strtok(NULL, "\n");

    /* finally, print each string using printf() for formatting    */
    //printf("%-25s %-20s %-15s %-15s\n", fld1, fld2, fld3, fld4);
  }
  fclose(fin);
  //return 0;
}

I get a segmentation fault
thanks in advance Mick

You don't check whether the file was successfully opened. You probably want to do so.
