I have seen quite a few posts recently which have launched into questions about specfic errors whose resolution depends a lot upon the OS type and version.
I suggest that in the FAQ an additional entry be included, either under general board usage or posting threads, that informs the user to... (6 Replies)

Hello,
We are planning a migration from UNIX (HP-UX, AIX, Solaris) to Linux on AZURE.
I know it sounds like extremely complicated :( That's why we need your help :)
We are at the beggining of stage.
We need to categorize the types of applications (software) that generally runs on UNIX... (3 Replies)

curlopt_unix_socket_path
CURLOPT_UNIX_SOCKET_PATH(3) curl_easy_setopt options CURLOPT_UNIX_SOCKET_PATH(3)NAME
CURLOPT_UNIX_SOCKET_PATH - set Unix domain socket
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_UNIX_SOCKET_PATH, char *path);
DESCRIPTION
Enables the use of Unix domain sockets as connection endpoint and sets the path to path. If path is NULL, then Unix domain sockets are dis-
abled. An empty string will result in an error at some point, it will not disable use of Unix domain sockets.
When enabled, curl will connect to the Unix domain socket instead of establishing a TCP connection to a host. Since no TCP connection is
created, curl does not need to resolve the DNS hostname in the URL.
The maximum path length on Cygwin, Linux and Solaris is 107. On other platforms it might be even less.
Proxy and TCP options such as CURLOPT_TCP_NODELAY(3) are not supported. Proxy options such as CURLOPT_PROXY(3) have no effect either as
these are TCP-oriented, and asking a proxy server to connect to a certain Unix domain socket is not possible.
The application does not have to keep the string around after setting this option.
DEFAULT
Default is NULL, meaning that no Unix domain sockets are used.
PROTOCOLS
All protocols except for file:// and FTP are supported in theory. HTTP, IMAP, POP3 and SMTP should in particular work (including their
SSL/TLS variants).
EXAMPLE
Given that you have an nginx server running, listening on /tmp/nginx.sock, you can request a HTTP resource with:
curl_easy_setopt(curl_handle, CURLOPT_UNIX_SOCKET_PATH, "/tmp/nginx.sock");
curl_easy_setopt(curl_handle, CURLOPT_URL, "http://localhost/");
If you are on Linux and somehow have a need for paths larger than 107 bytes, you could use the proc filesystem to bypass the limitation:
int dirfd = open(long_directory_path_to_socket, O_DIRECTORY | O_RDONLY);
char path[108];
snprintf(path, sizeof(path), "/proc/self/fd/%d/nginx.sock", dirfd);
curl_easy_setopt(curl_handle, CURLOPT_UNIX_SOCKET_PATH, path);
/* Be sure to keep dirfd valid until you discard the handle */
AVAILABILITY
Since 7.40.0.
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
