CURLINFO_CONTENT_TYPE(3)   Library Functions Manual   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 is set to 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.

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

PROTOCOLS
       HTTP

EXAMPLE
       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);
         }
       }
