CURLINFO_CONTENT_TYPE \- get Content\-Type

.SH SYNOPSIS

#include <curl/curl.h>

.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.
