.B CURLOPT_WRITEFUNCTION

Function pointer that should match the following prototype:

.BI "size_t function( void *ptr, size_t size, size_t nmemb, void *stream);"

This function gets called by libcurl as soon as there is received data that

needs to be written down. The size of the data pointed to by \fIptr\fP is

\fIsize\fP multiplied with \fInmemb\fP.  Return the number of bytes actually

written or return -1 to signal error to the library (it will cause it to abort

the transfer with CURLE_WRITE_ERROR).
