.TH CURLOPT_PORT 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_PORT \- set remote port number to work with
|
|
.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, "http://example.com/foo.bin");
|
|
curl_easy_setopt(curl, CURLOPT_PORT, 8080L);
|
|
ret = curl_easy_perform(curl);
