.SH NAME
CURLINFO_CONTENT_TYPE \- get Content\-Type
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_TYPE, char **ct);
.fi
.SH DESCRIPTION
Pass a pointer to a char pointer to receive the content\-type of the downloaded
object. This is the value read from the Content\-Type: field. If you get NULL,
it means that the server did not send a valid Content\-Type header or that the
protocol used does not support this.

The \fBct\fP pointer is set to NULL or pointing to private memory. You MUST
NOT free it \- it gets freed when you call \fIcurl_easy_cleanup(3)\fP on the
corresponding CURL handle.

The modern way to get this header from a response is to instead use the
\fIcurl_easy_header(3)\fP function.
