CURLOPT_UNIX_SOCKET_PATH(3)

curl_easy_setopt options                           CURLOPT_UNIX_SOCKET_PATH(3)



NAME
       CURLOPT_UNIX_SOCKET_PATH - Unix domain socket

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_UNIX_SOCKET_PATH, char *path);

DESCRIPTION
       Enables  the use of Unix domain sockets as connection endpoint and sets
       the path to path. If path is NULL, then Unix domain  sockets  are  dis‐
       abled.  An  empty string will result in an error at some point, it will
       not disable use of Unix domain sockets.

       When enabled, curl will connect to the Unix domain  socket  instead  of
       establishing  a  TCP  connection  to a host. Since no TCP connection is
       created, curl does not need to resolve the DNS hostname in the URL.

       The maximum path length on Cygwin, Linux and Solaris is 107.  On  other
       platforms it might be even less.

       Proxy and TCP options such as CURLOPT_TCP_NODELAY(3) are not supported.
       Proxy options such as CURLOPT_PROXY(3) have no effect either  as  these
       are  TCP-oriented,  and  asking  a proxy server to connect to a certain
       Unix domain socket is not possible.

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

DEFAULT
       Default is NULL, meaning that no Unix domain sockets are used.

PROTOCOLS
       All  protocols  except  for FILE and FTP are supported in theory. HTTP,
       IMAP, POP3 and SMTP should in particular work (including their  SSL/TLS
       variants).

EXAMPLE
       Given   that   you   have   an   HTTP   server   running  listening  on
       /tmp/httpd.sock, you can request an HTTP resource with:

         curl_easy_setopt(curl_handle, CURLOPT_UNIX_SOCKET_PATH, "/tmp/httpd.sock");
         curl_easy_setopt(curl_handle, CURLOPT_URL, "http://localhost/");

       If you are on Linux and somehow have a need for paths larger  than  107
       bytes, you could use the proc filesystem to bypass the limitation:

         int dirfd = open(long_directory_path_to_socket, O_DIRECTORY | O_RDONLY);
         char path[108];
         snprintf(path, sizeof(path), "/proc/self/fd/%d/httpd.sock", dirfd);
         curl_easy_setopt(curl_handle, CURLOPT_UNIX_SOCKET_PATH, path);
         /* Be sure to keep dirfd valid until you discard the handle */

AVAILABILITY
       Added in 7.40.0.

RETURN VALUE
       Returns  CURLE_OK  if the option is supported, and CURLE_UNKNOWN_OPTION
       if not.
