CURLOPT_DNS_SERVERS3
Dns servers to use
Usage
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_SERVERS, char *servers);
Overview
Pass a char pointer that is the list of DNS servers to be used instead of the system default. The format of the dns servers option is:
host[:port][,host[:port]]...
For example:
192.168.1.100,192.168.1.101,3.4.5.6
The application does not have to keep the string around after setting this option.
Default
NULL - use system default
Protocols
All
Examples
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
curl_easy_setopt(curl, CURLOPT_DNS_SERVERS,
"192.168.1.100:53,192.168.1.101");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
Return value
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, CURLE_NOT_BUILT_IN if support was disabled at compile-time, CURLE_BAD_FUNCTION_ARGUMENT when given an invalid server list, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
