=head1 DESCRIPTION
|
|
|
|
|
|
|
|
|
|
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().
|
|
|
|
|
|
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
|
|
|
|
|
|
If non-NULL, SSL_group_to_name() returns the TLS group name
|
2021-10-22 15:32:23 +08:00
|
|
|
corresponding to the given I<id> as a NUL-terminated string.
|
2021-01-07 16:09:32 +08:00
|
|
|
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 I<ssl>.
