.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBSSL_group_to_name()\fR 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 \fBSSL_get1_groups()\fR
or \fBSSL_get_shared_group()\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
If non-NULL, \fBSSL_group_to_name()\fR returns the TLS group name
corresponding to the given \fIid\fR as a NUL-terminated string.
If \fBSSL_group_to_name()\fR returns NULL, an error occurred; possibly no
corresponding tlsname was registered during provider initialisation.
.PP
Note that the return value is valid only during the lifetime of the
SSL object \fIssl\fR.
