Okay now, I have been using the DJGPP compiler with rhide ever since I
downloaded DJGPP. Nothing has failed me, (but then again, no really big
programs...) I am wrtting this game, and in order to load up some data, I
need to store it in a file of record. (or structers...) Now, I have written
3 demo programs to see why MOST of the time Rhide crashes. I thought it was
from me, and maybe I was making some little syntax
mistake. No, it doesn't appear that way. I am getting every frustrated with
this, but I am asking for some assistance. Here are are 2 programs I have
written, to test rhide and see if it is ride it self or if its djgpp.
Most of the time they DON'T work, but if I run the same program 2 times in
a row, it works fine... :(

--- cut --- filetst.c ------

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>


// before running this program, create a text file called 'test.txt'
// and put in  2 integers on 2 diffrant lines, then a string value.
// like so:


// 100
// 100
// blahblahblah

struct blah {
   int x, y;
   char *name;
};
struct blah *testing;
main () {
   FILE *fp;


   testing->name = " ";
   printf("\n\nReading straight from text file.\n\n ");
   if ((fp = fopen("test.txt", "r")) != NULL) {
      fscanf(fp, "%d", &testing->x);
      fscanf(fp, "%d", &testing->y);
      fscanf(fp, "%s", testing->name);
      fclose(fp);
      printf("%d-%d-%s", testing->x, testing->y, testing->name);
   }
   else {
      printf("not able to open file.\n");
      return(0);
   }
   printf("\n\nWritting straight to binary file.\n\n ");
   if ((fp = fopen("test.out", "wb")) != NULL) {
      fwrite(testing, sizeof(testing), 1, fp);
      fclose(fp);
   }

   testing->name = " ";
   printf("\n\nReading straight from binary file.\n\n ");
   if ((fp = fopen("test.out", "rb")) != NULL) {
      fread(testing, sizeof(testing), 1, fp);
      fclose(fp);
      printf("%d-%d-%s", testing->x, testing->y, testing->name);
   }

}

contain the following

the object,
// a number telling if it is an animation, (0 or 1,) then a frame number,
then the list of
// bitmap files...
