I am trying to convert a binary file to a pdb file . The binary file
contains 1230 records but when the created database is uploaded on the
device the rec count is only 95
Can anyone help me out
I just downloaded the code from some site
#include "stdafx.h"
void fopen_error (char* file_name);
void exit ();
# include <stdio.h>
//PUT RECORD SIZE HERE
#define REC_SIZE 42
#define invert32(x) (((x & 0x000000ff)<<24) | ((x & 0x0000ff00)<<8) | ((x &
0x00ff0000)>>8) | ((x & 0xff000000) >> 24))
#define invert16(x) (((x & 0x00ff)<<8) | ((x & 0xff)>>8))
