CURLOPT_NETRC_FILE(3) Introduction to Library Functions

NAME

CURLOPT_NETRC_FILE - filename to read .netrc info from

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NETRC_FILE, char *file);

DESCRIPTION

Pass a char pointer as parameter, pointing to a null-terminated
string containing the full path name to the file you want libcurl to
use as .netrc file. If this option is omitted, and CURLOPT_NETRC(3)
is set, libcurl checks for a .netrc file in the current user's home
directory.

The application does not have to keep the string around after setting
this option.

Using this option multiple times makes the last set string override
the previous ones. Set it to NULL to disable its use again.

DEFAULT

NULL

PROTOCOLS

This functionality affects all supported protocols

EXAMPLE

int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode result;
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/");
curl_easy_setopt(curl, CURLOPT_NETRC, CURL_NETRC_OPTIONAL);
curl_easy_setopt(curl, CURLOPT_NETRC_FILE, "/tmp/magic-netrc");
result = curl_easy_perform(curl);
}
}
