                     31: .SH DESCRIPTION
                     32: Pass a pointer to a char pointer to receive the content-type of the downloaded
                     33: object. This is the value read from the Content-Type: field. If you get NULL,
                     34: it means that the server didn't send a valid Content-Type header or that the
                     35: protocol used doesn't support this.
                     36: 
                     37: The \fBct\fP pointer will be NULL or pointing to private memory you MUST NOT
                     38: free it - it gets freed when you call \fIcurl_easy_cleanup(3)\fP on the
                     39: corresponding CURL handle.
