Thread: Please help me with this !! Emergency

I have this code

Code:

/*checking if the products in supplyfile correspond in real products*/
void runF22(int N)
{
	int i=0,found, productnummax,productnum=0;
	char line[1000],*f;
	char Msg05[]="The product code doesn't exist";
	struct Sys_Rec a;
	struct Prod_Rec b, B[Prod_Items_max];
	FILE *p_product, *p_sys;

	/* we open sys.dat to find product max number*/
	/* and products File name to open it*/
	p_sys=fopen("sys.dat","r");
	while(!feof(p_sys)){
		fscanf(p_sys,"%d %d %s %d %s %d %d %s",&a.Sys_WhNum,
	   &a.Sys_ProdNum,a.Sys_WhFN,&a.Sys_StorVol,a.Sys_ProdFN,
           &a.Sys_SupMaxItems,&a.Sys_OrdMaxItems,a.Sys_VolDescr);
	}
	productnummax=a.Sys_ProdNum;

	f=a.Sys_ProdFN;
	fclose(p_sys);
	p_product=fopen(f,"r");

	/* cheking if product file is empty*/
	if(p_product==NULL){
		printf("error reading product file");
		exit(5);
	}

	/*open product file and create an array B to store objects*/
	/* and find the number of product exists*/
	while(fgets(line,998,p_product)){
		int ret;
		ret=sscanf(line,"%d %s %d %s", &b.Prod_Code,b.Prod_Descr,
		&b.Prod_Vol,b.Prod_Storage_Option);

		B[productnum]=b;               /*store in array B if line is Ok*/
		productnum++;
		if(productnum==productnummax) break;  /*don't read too many*/
	}


	/*checking if all items for import exist as product*/
	i=0;found=0;
	while(i<productnum && found==0){
			if(B[i].Prod_Code==N)found=1;
			i++;
		}
	if(found==0){
		fprintf(stderr,Msg05); /*not real product for import*/
	    exit(5);
	}
	else
		return;   /*if the item exist to F21 to continue*/
}

CAN SOMENONE TELL ME A LIST OF CHARACTERISTICS THAT NEED TO BE CHECKED IF WE WANT TO CONTROL (CHECK) THAT THE CODE IS RIGHT ??
