+\& BIGNUM *BN_copy(BIGNUM *to, const BIGNUM *from);

+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBBN_copy()\fR copies \fBfrom\fR to \fBto\fR. \fBBN_dup()\fR creates a new \fBBIGNUM\fR
+containing the value \fBfrom\fR.
+.PP
+BN_with_flags creates a \fBtemporary\fR shallow copy of \fBb\fR in \fBdest\fR. It places
+significant restrictions on the copied data. Applications that do no adhere to
+these restrictions may encounter unexpected side effects or crashes. For that
+reason use of this function is discouraged. Any flags provided in \fBflags\fR will
+be set in \fBdest\fR in addition to any flags already set in \fBb\fR. For example this
+might commonly be used to create a temporary copy of a BIGNUM with the
+\&\fBBN_FLG_CONSTTIME\fR flag set for constant time operations. The temporary copy in
+\&\fBdest\fR will share some internal state with \fBb\fR. For this reason the following
+restrictions apply to the use of \fBdest\fR:
+.IP \(bu 2
+\&\fBdest\fR should be a newly allocated BIGNUM obtained via a call to \fBBN_new()\fR. It
+should not have been used for other purposes or initialised in any way.
+.IP \(bu 2
+\&\fBdest\fR must only be used in "read-only" operations, i.e. typically those
+functions where the relevant parameter is declared "const".
+.IP \(bu 2
+\&\fBdest\fR must be used and freed before any further subsequent use of \fBb\fR
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBBN_copy()\fR returns \fBto\fR on success, NULL on error. \fBBN_dup()\fR returns
+the new \fBBIGNUM\fR, and NULL on error. The error codes can be obtained
+by \fBERR_get_error\fR\|(3).
