Hi every1. Whats up?
I need to make a copy program so I wrote below code.
I compile it in HUGE memory model.
The problem occurs when the buffer size is over 60000 bytes.
Does fread or fwrite have some limitations?  Plz help.
Plz Plz Plz help.
#include
#include
#include
void copy()
{
unsigned long buf_num,fsize=1212409;  /* change fsize to your file size */
char *buf;
FILE *in,*out;
in=fopen("tc30.arj","rb");   /* change tc30.arj to some of your files */
out=fopen("test.arj","wb");  /* output file */
buf_num=coreleft();   /* If memory left is bellow 60000 it will work! */
if(buf_num>fsize) buf_num=fsize;
buf=(char*)malloc(buf_num);
while(fsize)
{
  fread(buf,buf_num,1,in);
  fwrite(buf,buf_num,1,out);
  fsize-=buf_num;
  if(fsize)
    if(buf_num>fsize) buf_num=fsize;
 }
free(buf);
fcloseall();
}

 BV> but remains the question 'what exactly is consuming more space'.
The heirarchy structure most likely - and the fact that each level is it's
own entity can't be easy to do.
