CURLINFO_CONTENT_TYPE(3)

NAME
CURLINFO_CONTENT_TYPE - get Content-Type

SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_TYPE, char **ct);

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 ct pointer will be NULL or pointing to private memory you MUST NOT free it - it gets freed when you call curl_easy_cleanup(3) on the corresponding CURL handle.

PROTOCOLS
HTTP(S)

EXAMPLE
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);
}
