CURLOPT_PORT(3) libcurl CURLOPT_PORT(3)
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
By default this is 0 which makes it not used. This also makes port num-
ber zero impossible to set with this API.
PROTOCOLS
Used for all protocols that speak to a port number.
EXAMPLE
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);
}
AVAILABILITY
Always
RETURN VALUE
Returns CURLE_OK
