- HTTrack external callbacks example : dumy plugin, aimed to log for debugging purpose
-
- How to build: (callback.so or callback.dll)
- With GNU-GCC:
- gcc -O -g3 -Wall -D_REENTRANT -shared -o mycallback.so callbacks-example.c -lhttrack1
- With MS-Visual C++:
- cl -LD -nologo -W3 -Zi -Zp4 -DWIN32 -Fe"mycallback.dll" callbacks-example.c libhttrack1.lib
-
- Note: the httrack library linker option is only necessary when using libhttrack's functions inside the callback
-
- How to use:
- httrack --wrapper mycallback ..
