NAME

       CURLOPT_PORT - remote port number to connect to

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PORT, long number);

DESCRIPTION

       We  discourage  using  this  option since its scope is not obvious and hard to predict. Set the preferred
       port number in the URL instead.

       This option sets number to be the remote port number to connect to, instead of the one specified  in  the
       URL or the default port for the used protocol.

       Usually, you just let the URL decide which port to use but this allows the application to override that.

       While this option accepts a 'long', a port number is an unsigned 16 bit number and therefore using a port
       number lower than zero or over 65535 causes a CURLE_BAD_FUNCTION_ARGUMENT error.

DEFAULT

       0 which makes it not used. This also makes port number zero impossible to set with this API.

PROTOCOLS

       This functionality affects all supported protocols

EXAMPLE

       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_PORT, 8080L);
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }
