CURLINFO_CONTENT_TYPE(3)            libcurl           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);
       }
