CURLOPT_ABSTRACT_UNIX_SOCKET(3) Library Functions Manual
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.
