Retrieving and Restoring Data Using the LAN
Example This C program strips the LIF structure from the data.raw file.
#include <stdio.h>
main(int argc, char *argv[] )
{ char buffer[256] ;
int len ;
int count = 0 ;
while (( len = read( 0, buffer, 256 ))>0 ) {
count++ ;
switch ( count ) {
case 1:
case 2:
/* do nothing -- just throw away */
break;
case 3:
/*
** throw away the first two bytes(record size)
** the next four bytes ( file type ? )
** the next 32 bytes ( file description )
*/
if ( len - 38 >0 )
write( 1, &buffer[38], len-38 ) ;
break;
default:
/*throw away the first two bytes(record size)*/
len = (unsigned char)buffer[1] ;
if ( len > 0 )
write( 1, &buffer[2], len ) ;
break;
