CURLINFO_CONTENT_TYPE(3)





CURLINFO_CONTENT_TYPE(3curl_easy_getinfo optionCURLINFO_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  didn't  send a valid Content-Type header or that the
     protocol used doesn't 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, "http://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
