- always assign the curl_easy_perform() return code (and declare the necessary 'result' variable for it) - always call curl_easy_cleanup() on the created easy handles Closes #21364

# NAME
|
|
|
|
CURLOPT_ABSTRACT_UNIX_SOCKET - abstract Unix domain socket
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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

|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode result;
|
|
curl_easy_setopt(curl, CURLOPT_ABSTRACT_UNIX_SOCKET, "/tmp/foo.sock");
|
|
curl_easy_setopt(curl, CURLOPT_URL, "http://localhost/");
|
|
|
|
/* Perform the request */
|
|
result = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}
