.TH CURLOPT_ABSTRACT_UNIX_SOCKET 3 "08 Jan 2017" "libcurl 7.53.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_ABSTRACT_UNIX_SOCKET \- set an abstract Unix domain socket
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ABSTRACT_UNIX_SOCKET, char *path);
.SH 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 zero terminated string
holding the path of the socket. The path will be set to \fIpath\fP 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
.BR 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.

.SH DEFAULT
Default is NULL.
.SH EXAMPLE
.nf
    curl_easy_setopt(curl_handle, CURLOPT_ABSTRACT_UNIX_SOCKET, "/tmp/foo.sock");
    curl_easy_setopt(curl_handle, CURLOPT_URL, "http://localhost/");
.fi

.SH AVAILABILITY
Since 7.53.0.
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
