How to printout CURL_VERSION_UNIX_SOCKETS

Hello world.

In curl.h

> #define CURL_VERSION_UNIX_SOCKETS (1<<19) /* Unix domain sockets support */

In https://curl.se/libcurl/c/curl_version_info.html

So from here, we can print out CURL_VERSION_UNIX_SOCKETS to 7.40.0?

Here is what I tried:
    printf("CURL_VERSION_UNIX_SOCKETS  version: %u.%u.%u\n"
        ,(CURL_VERSION_UNIX_SOCKETS >> 19 ) & 0xff
        ,(CURL_VERSION_UNIX_SOCKETS  >> 16) & 0xff
        ,(CURL_VERSION_UNIX_SOCKETS >> 8) & 0xff
    );

it print out: CURL_VERSION_UNIX_SOCKETS  version: 1.8.0

So it failed.
overall, I don't understand: #define CURL_VERSION_UNIX_SOCKETS (1<<19) /*
Unix domain sockets support */
