.TH CURLOPT_PORT 3 "17 Jun 2014" libcurl libcurl
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_PORT \- remote port number to connect to
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PORT, long number);
|
||
|
|
.fi
|
||
|
|
.SH 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 \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 an unsigned 16 bit number
|
||
|
|
and therefore using a port number lower than zero or over 65535 causes a
|
||
|
|
\fBCURLE_BAD_FUNCTION_ARGUMENT\fP error.
|
||
|
|
.SH DEFAULT
|
||
|
|
By default this is 0 which makes it not used. This also makes port number zero
|
||
|
|
impossible to set with this API.
|
||
|
|
.SH PROTOCOLS
|
||
|
|
Used for all protocols that speak to a port number.
|
||
|
|
.SH EXAMPLE
|
||
|
|
