CURLOPT_ABSTRACT_UNIX_SOCKET(3) Introduction to Library Functions
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
curl_easy_setopt(3) returns a CURLcode indicating success or error.
CURLE_OK (0) means everything was OK, non-zero means an error
occurred, see
libcurl-errors(3).
