14
15SSL_group_to_name() is used to retrieve the TLS group name
16associated with a given TLS group ID, as registered via built-in
17or external providers and as returned by a call to SSL_get1_groups()
18or SSL_get_shared_group().
19
20=head1 RETURN VALUES
21
22If non-NULL, SSL_group_to_name() returns the TLS group name
23corresponding to the given I<id> as a NUL-terminated string.
24If SSL_group_to_name() returns NULL, an error occurred; possibly no
25corresponding tlsname was registered during provider initialisation.
26
27Note that the return value is valid only during the lifetime of the
28SSL object I<ssl>.
