SSL_group_to_name - get name of group
#include <openssl/ssl.h>
const char *SSL_group_to_name(const SSL *ssl, int id);
SSL_group_to_name() is used to retrieve the TLS group name associated
with a given TLS group ID, as registered via built-in or external providers
and as returned by a call to SSL_get1_groups() or
SSL_get_shared_group().
If non-NULL, SSL_group_to_name() returns the TLS group name corresponding
to the given id as a NUL-terminated string. If
SSL_group_to_name() returns NULL, an error occurred; possibly no
corresponding tlsname was registered during provider initialisation.
Note that the return value is valid only during the lifetime of
the SSL object ssl.
