SSL_group_to_name - get name of group

#include <openssl/ssl.h>
const char *SSL_group_to_name(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.
