/*
HTTrack external callbacks example : changing the destination filename
.c file
How to use:
- compile this file as a module (callback.so or callback.dll)
example:
(with gcc)
gcc -O -g3 -Wall -D_REENTRANT -DINET6 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -shared -o callback.so callbacks-example-filename.c
or (with visual c++)
cl -LD -nologo -W3 -Zi -Zp4 -DWIN32 -Fe"callback.dll" callbacks-example-filename.c
- use the --wrapper option in httrack:
httrack --wrapper save-name=callback:mysavename
*/
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
/* "External" */
#ifdef _WIN32

/* TOLOWER */
#define TOLOWER_(a) (a >= 'A' && a <= 'Z') ? (a + ('a' - 'A')) : a
#define TOLOWER(a) ( TOLOWER_( (a) ) )
/*
This sample just changes the destination filenames to ROT-13 equivalent ; that is,
a -> n
b -> o
c -> p
d -> q
..
n -> a
o -> b
..
<parent> -> <link>
This sample can be improved, for example, to make a map of a website.
