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(S)

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);
         }
       }
