HTTrack library example
.c file
Prerequisites:
- install winhttrack
- set the proper path in the project settings (especially for the httrack lib and dll)
How to build: (callback.so or callback.dll)
With GNU-GCC:
gcc -I/usr/include/httrack -O -g3 -Wall -D_REENTRANT -o example example.c -lhttrack2
With MS-Visual C++:
cl -nologo -W3 -Zi -Zp4 -DWIN32 -Fe"mycallback.exe" callbacks-example.c wsock32.lib libhttrack.lib
