NAMECURLOPT_NETRC − enable use of .netrc
SYNOPSIS#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NETRC, long level);
DESCRIPTIONThis parameter controls the preference level of libcurl between using user names and passwords from your ~/.netrc file, relative to user names and passwords in the URL supplied with CURLOPT_URL(3). On Windows, libcurl will use the file as %HOME%/_netrc, but you can also tell libcurl a different file name to use with CURLOPT_NETRC_FILE(3). libcurl uses a user name (and supplied or prompted password) supplied with CURLOPT_USERPWD(3) or CURLOPT_USERNAME(3) in preference to any of the options controlled by this parameter. Only machine name, user name and password are taken into account (init macros and similar things are not supported). libcurl does not verify that the file has the correct properties set (as the standard Unix ftp client does). It should only be readable by user. level is a long that should be set to one of the values described below. CURL_NETRC_IGNORED (0) The library will ignore the .netrc file. This is the default. CURL_NETRC_OPTIONAL (1) The use of the .netrc file is optional, and information in the URL is to be preferred. The file will be scanned for the host and user name (to find the password only) or for the host only, to find the first user name and password after that machine, which ever information is not specified. CURL_NETRC_REQUIRED (2) The use of the .netrc file is required, and any credential information present in the URL is ignored. The file will be scanned for the host and user name (to find the password only) or for the host only, to find the first user name and password after that machine, which ever information is not specified.
