Hello,

There were many messages about a bug in C++ with packed structures a
few time ago. I've forgotten the solution. It seems to me that i have
to use #pragma packed(1) but i can't manage to have this program work.

#include <stdio.h>

#pragma packed(1)
#include <dir.h>              // struct ffblk is packed
#pragma packed(0)

int main(void)
{
   struct ffblk ffblk;
   int done;
   printf("Directory listing of *.*\n");
   done = findfirst("*.*",&ffblk,0);
   while (!done)
   {
	  printf("  %s\n", ffblk.ff_name);  // ff_name is too bytes to big ->
the first two characters of the filename are lost
	  done = findnext(&ffblk);
   }
   return 0;
}
