curl_version(3)             Library Functions Manual            curl_version(3)

NAME
       curl_version - returns the libcurl version string

SYNOPSIS
       #include <curl/curl.h>

       char *curl_version();

DESCRIPTION
       Returns  a  human readable string with the version number of libcurl and
       some of its important components (like OpenSSL version).

       For MultiSSL builds the string contains all SSL backend  names  and  the
       inactive  backend names are in parentheses. For example "(OpenSSL/3.0.8)
       Schannel" or "OpenSSL/3.0.8 (Schannel)".

       We recommend using curl_version_info(3) instead.

PROTOCOLS

EXAMPLE
       int main(void)
       {
         printf("libcurl version %s\n", curl_version());

RETURN VALUE
       A pointer to a null-terminated string. The string resides  in  a  stati-
       cally allocated buffer and must not be freed by the caller.
