# NAME

CURLINFO_CONTENT_TYPE - Content-Type of response

# SYNOPSIS

~~~c
#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 is NULL or points to private memory. You **must not** free
it. It gets freed automatically when you call curl_easy_cleanup(3) on the
corresponding curl handle.

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

# %PROTOCOLS%

# EXAMPLE

~~~c
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    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);
  }
}
~~~

# %AVAILABILITY%

# RETURN VALUE

curl_easy_getinfo(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
libcurl-errors(3).
