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  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

       This functionality affects http only

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);
         }
       }
