Thread: Nested Structures

I am trying to back up windows file attributes using a nested structure to save the path and file name along with the windows attributes structure. I have simplifed the code to the snippet below. Compile (gcc) gives
error: field `attr_struct' has incomplete type.

Assistnace will be very much appreciated.

Code:

#include <stdio.h>
#include <windows.h>

FILE *out;

int get_attrs(char *dir)
{
  int result;
  char char_buffer[500];
  char char_dir[500];
  char shortpath[500];
  WIN32_FIND_DATA FindFileData;
  HANDLE hFind;

  struct file_attrs {
    char filename[500];
    struct WIN32_FIND_DATA attr_struct;
  } file_data;

  strcpy(char_buffer,dir);
  strcat(char_buffer,"\\*.*");

  hFind = FindFirstFile(char_buffer, &FindFileData);

  do
  {  
    if (!strcmp(FindFileData.cFileName, ".")) 
      continue;
    if (!strcmp(FindFileData.cFileName, "..")) 
      continue;

    strcpy(file_data.filename, char_buffer);
    file_data.attr_struct = FindFileData;
    fwrite(&file_data, sizeof(file_data),1, out);

  } while (FindNextFile(hFind, &FindFileData));
  FindClose(hFind);
}

int main(void)
{
  out = fopen("attrs.dat", "w");
  if ( out == NULL)
  {
    printf("could not open attrs.dat");
    exit(1);
  }
  get_attrs("d:\\c_projects");
  fclose(out);
  exit(0);
}
