+# NAME
+
+CURLOPT_ABSTRACT_UNIX_SOCKET - abstract Unix domain socket
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ABSTRACT_UNIX_SOCKET,
+                          char *path);
+~~~
+
+# DESCRIPTION
+
+Enables the use of an abstract Unix domain socket instead of establishing a
+TCP connection to a host. The parameter should be a char * to a
+null-terminated string holding the path of the socket. The path is set to
+*path* prefixed by a NULL byte. This is the convention for abstract
+sockets, however it should be stressed that the path passed to this function
+should not contain a leading NULL byte.
+
+On non-supporting platforms, the abstract address is interpreted as an empty
+string and fails gracefully, generating a runtime error.
+
+This option shares the same semantics as CURLOPT_UNIX_SOCKET_PATH(3) in
+which documentation more details can be found. Internally, these two options
+share the same storage and therefore only one of them can be set per handle.
+
+# DEFAULT
+
+NULL
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    curl_easy_setopt(curl, CURLOPT_ABSTRACT_UNIX_SOCKET, "/tmp/foo.sock");
+    curl_easy_setopt(curl, CURLOPT_URL, "http://localhost/");
+
+    /* Perform the request */
+    curl_easy_perform(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
