Hi,

I am trying to write a small program to detect the number of files in a
directory and the filenames

/* Quick and dirty test routine */
#define MAX_FILE 1000

void main()
{
  int i;
  char fn[MAX_FILE][256];
  DIR *path;
  struct dirent *dir;
  path = opendir("c:/test");
  while((dir = readdir(path))) {
    fn[++i] = dir->d_name;
  }
}

Ok, the above works fine but when MAX_FILE is *larger*, it return err 255.
Then I came to the idea of using pointer b'cos it can hold large data
  char *fn[256]
  ...
    ++*fn = dir->d_name;
  ...
Somebody would propably laughing already! After a idiotic trial and error, I
found out that the dir->d_name has the same address each time. So I endup
getting a list of the same (last)filename in fn b'cos each *fn is the SAME.
After that, I though of writing the output to a file could solve the
prob(Haven't try yet) but I don't want to.

Can anybody help me how to create a large array to hold each filename (IF
file numbers way way larger)

Thanx in advance.
