Does anyone have a piece of code that can write to a file on the memory stick from an array and them read it back into an array?

I had a problem with trying to do this before, for some reason when I tried to save my entire static array, it would save fine, but when I went to load it, it didn't load it correctly. I'm not sure if it has to do with endianness. What I ended up doing is just save and read them one at a time thru an array

It is a 100 int array

Code:
/********************************/

int   load_keys(int file)
{
   char path_ini[MAXPATH], KeyFile [] = { 'K', 'E', 'Y', '0', 0 };
   int fd;

   mh_strncpy( ini_data.path, now_path, MAXPATH);

   KeyFile[3] += file;
   _strcpy( path_ini, path_main);
   _strcat( path_ini, KeyFile);
   fd = sceIoOpen(path_ini,O_RDONLY, 0777);
   if(fd>=0){
      sceIoRead(fd, &ini_data.key, sizeof(int)*100);
      sceIoClose(fd);
      return 1;
   }
   return 0;
}

int   save_keys(int file)
{
   int fd;
   char path_ini[MAXPATH], KeyFile [] = { 'K', 'E', 'Y', '0', 0 };

   mh_strncpy( ini_data.path, now_path, MAXPATH);

   KeyFile[3] += file;
   _strcpy( path_ini, path_main);
   _strcat( path_ini, KeyFile);
   
   fd = sceIoOpen(path_ini,O_RDONLY, 0777);
   if(fd>=0){
      sceIoClose(fd);
      
      unsigned long key;
      char msg[] = { "Overwrite Key Profile 1? : OK ~: CANCEL" };
                  
      msg[22] += file;
      do
      {
         pgFillvram(0);
         text_print(100,100, msg,rgb2col(250,80,80),0,0);
         pgScreenFlipV();
         
         
         key = Read_Key();
         if(CTRL_CROSS & key)
            return 2;
         pgWaitV();
      }
      while(!(key & CTRL_CIRCLE));
      
   }
   
   fd = sceIoOpen( path_ini, O_CREAT|O_WRONLY|O_TRUNC, 0777);
   if(fd>=0){
      sceIoWrite(fd, &ini_data.key, sizeof(int)*100);
      sceIoClose(fd);
      return 1;
   }
   return 0;
}

i guess you need to lose some &'s, but without data structures it's difficult to be sure.

... and your data manipulation techniques are scary.
