Subject: Emulator vs RealDevice
Hello Everybody,
I am facing a very strange problem.
I have made a pdb file using the docs availbale for pdb file.
The file when uploaded on the emulator displays the records as 4059 and
size 151k
but when the file is hotsync to the palm device palm m105 the size
reduces to 13k and the records are 256.
I am totally confused by this behaviour ,
I am enclosing the source
#include <iostream.h>
#include <io.h>
#include <fcntl.h>
#include <sys\stat.h>
#include <errno.h>
#include <string.h>
#include <time.h>
#include <windows.h>

void exit ();
