.SH "DESCRIPTION"
\fIBN_copy()\fR copies \fBfrom\fR to \fBto\fR. \fIBN_dup()\fR creates a new \fBBIGNUM\fR
containing the value \fBfrom\fR.
.SH "RETURN VALUES"
\fIBN_copy()\fR returns \fBto\fR on success, NULL on error. \fIBN_dup()\fR returns
the new \fBBIGNUM\fR, and NULL on error. The error codes can be obtained
by the \fIERR_get_error(3)|ERR_get_error(3)\fR manpage.
.SH "SEE ALSO"
the \fIbn(3)|bn(3)\fR manpage, the \fIerr(3)|err(3)\fR manpage
.SH "HISTORY"
\fIBN_copy()\fR and \fIBN_dup()\fR are available in all versions of SSLeay and OpenSSL.
