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.

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);
  }
}
