NAME

       CURLOPT_ABSTRACT_UNIX_SOCKET - abstract Unix domain socket

SYNOPSIS

       #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

       This functionality affects all supported protocols

EXAMPLE

       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

       Added in curl 7.53.0

RETURN VALUE

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