HTTrack external callbacks example : display all incoming request headers
|
|
Example of <wrappername>_init and <wrappername>_exit call (httrack >> 3.31)
|
|
.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 ..
