Function In C Not Working Right, Need Help

[Ghost2520]

So i'm workin on this project right now... due tomorrow.... not very far. Basically, I've got an input file that has schedule information in the following format.

 

c /*this is the course prefix */

121 /* course number */

4 /*number of credits */

8 /*number of seats */

 

The input file has 11 of these groups. I need to make a function that reads one in, and does error checking to make sure its to the proper format. If it is, it the function returns a 1 for true. If its not, a 0 is returned. The actual values of each variable are sent back via pointers. I haven't implemented any errorchecking yet, but for some reason I can't get the pointers working for the string. 121, 4 and 8 are sent back properly but the c gets returned as a bunch of garble.

 

 

I've actually decided it would probably be better to define my own types using structures... so I've got

 

typedef struct{
	  char course_prefix[5];
	  int course_number;
	 int credits;
	   int seats;
}course_t;

int get_course_record (FILE *infile, course_t *current_course); /* prototype */

result = get_course_record (sched_in, &current_course); /* function call */


/*Function definition: */

int
get_course_record (FILE *infile, course_t *current_course)
{
char scan_prefix[strSIZE];
int scan_course_number;
int scan_credits;
int scan_seats;

fscanf(infile, "%c", scan_prefix);
fscanf(infile, "%d", &scan_course_number);
fscanf(infile, "%d", &scan_credits);
fscanf(infile, "%d", &scan_seats);

strcopy((*current_course).course_prefix, scan_prefix); /* I'm not sure if this is correct syntax here */
(*current_course).course_number = scan_course_number;
(*current_course).credits = scan_credits;
(*current_course).seats = scan_seats;

return 1;
}

let me see the prototype and the call... thats the declaration ..
