 This function gets called by libcurl as soon as it has received header

 complete header lines are passed on to the callback. Parsing headers is very

 multiplied with \fInmemb\fP. Do not assume that the header line is zero
 terminated! The pointer named \fIuserdata\fP is the one you set with the
 \fICURLOPT_HEADERDATA(3)\fP option. This callback function must return the
 number of bytes actually taken care of. If that amount differs from the amount
 passed in to your function, it'll signal an error to the library. This will
