CURLOPT_ABSTRACT_UNIX_SOCKET - set an abstract Unix domain socket
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ABSTRACT_UNIX_SOCKET, char *path);
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 will be 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).
On non-supporting platforms, the abstract address will be interpreted as an empty string and fail gracefully, generating a run-time 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 is NULL.
curl_easy_setopt(curl_handle, CURLOPT_ABSTRACT_UNIX_SOCKET, "/tmp/foo.sock");
curl_easy_setopt(curl_handle, CURLOPT_URL, "http://localhost/");
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
