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

       Default is NULL.

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 7.53.0.

RETURN VALUE

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