Hi admin:

   Thank you for you reply .

The write_data() is a callback function, you mean the system will call the
function several times as long as it get the correct value ? but I use
breakpoint and find the function only called one time when it only receive
'1239' not '1246',Is there any other parament I have to set ?

   Thank you very much.

Best regards,
Kevin Liu

libcurl calls the function several times as long as you just return the
correct value, and then the sum of all calls should be the total body size.
