Jian,
I’m not sure what you’re trying to accomplish. CURL_VERSION_UNIX_SOCKETS is a
bit flag for features – not a version.
Try this:
auto data = curl_version_info(CURLVERSION_NOW);
printf("Curl version: %s\n", data->version);
if (data->features & CURL_VERSION_UNIX_SOCKETS)
printf("Curl supports UNIX sockets.\n");
else
printf("Curl does NOT support UNIX sockets.\n");

Subject: 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
CURL_VERSION_UNIX_SOCKETS
libcurl was built with support for Unix domain sockets. (Added in 7.40.0)
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 */
