.TH CURLINFO_CONTENT_TYPE 3 "September 26, 2023" "libcurl 8.4.0" "libcurl"

.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.
.SH PROTOCOLS
HTTP(S)
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

  res = curl_easy_perform(curl);

  if(!res) {
    /* extract the content-type */
    char *ct = NULL;
    res = curl_easy_getinfo(curl, CURLINFO_CONTENT_TYPE, &ct);
    if(!res && ct) {
      printf("Content-Type: %s\\n", ct);
    }
  }
  curl_easy_cleanup(curl);
}
.fi
.SH AVAILABILITY
