.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
|
2020-06-25 05:38:25 -04:00
|
|
|
connection to a host. The parameter should be a char * to a null-terminated string
|
2017-01-08 17:51:08 -05:00
|
|
|
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.
