.TH CURLOPT_PORT 3 "September 08, 2021" "libcurl 7.80.0" "curl_easy_setopt options"

.SH NAME
CURLOPT_PORT \- remote port number to connect to
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PORT, long number);
.SH DESCRIPTION
This option sets \fInumber\fP 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 usually a 16 bit number
and therefore using a port number over 65535 will cause a run-time error.
.SH DEFAULT
By default this is 0 which makes it not used.
.SH PROTOCOLS
Used for all protocols that speak to a port number.
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
  curl_easy_setopt(curl, CURLOPT_PORT, 8080L);
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}
.fi
.SH AVAILABILITY
Always
.SH RETURN VALUE
Returns CURLE_OK
