HTTrack external callbacks example : changing the destination filename
.c file
How to build: (callback.so or callback.dll)
With GNU-GCC:
gcc -O -g3 -Wall -D_REENTRANT -shared -o mycallback.so callbacks-example.c -lhttrack2
With MS-Visual C++:
cl -LD -nologo -W3 -Zi -Zp4 -DWIN32 -Fe"mycallback.dll" callbacks-example.c libhttrack.lib
Note: the httrack library linker option is only necessary when using libhttrack's functions inside the callback
How to use:
httrack --wrapper mycallback ..

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.
