/*
    HTTrack external callbacks example : changing folder names ending with ".com"
    with ".c0m" as a workaround of IIS bug (see KB 275601)

    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
