.TH CURLOPT_LOCALPORTRANGE 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_LOCALPORTRANGE \- number of additional local ports to try
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_LOCALPORTRANGE,
|
|
long range);
|
|
.SH DESCRIPTION
|
|
Pass a long. The \fIrange\fP argument is the number of attempts libcurl will
|
|
make to find a working local port number. It starts with the given
|
|
\fICURLOPT_LOCALPORT(3)\fP and adds one to the number for each retry. Setting
|
|
this option to 1 or below will make libcurl do only one try for the exact port
|
|
number. Port numbers by nature are scarce resources that will be busy at times
|
|
so setting this value to something too low might cause unnecessary connection
|
|
setup failures.

|
|
1
