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);
         }
       }
