BN_div_recp() divides B<a> by B<m> using B<recp>. It places the quotient
in B<dv> and the remainder in B<rem>.
-The B<BN_RECP_CTX> structure is defined as follows:
-
- typedef struct bn_recp_ctx_st
- {
- BIGNUM N; /* the divisor */
- BIGNUM Nr; /* the reciprocal */
- int num_bits;
- int shift;
- int flags;
- } BN_RECP_CTX;
-
-It cannot be shared between threads.

=head1 RETURN VALUES
For the other functions, 1 is returned for success, 0 on error.
The error codes can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>.
+=head1 REMOVED FUNCTIONALITY
+
+ void BN_RECP_CTX_init(BN_RECP_CTX *recp);
+
+BN_RECP_CTX_init() is no longer available as of OpenSSL 1.1.0. It was used to
+initialize an existing uninitialized B<BN_RECP_CTX>. Typically this would be
+done as follows:
+
+ BN_RECP_CTX ctx;
+ BN_RECP_CTX_init(&ctx);
+
+Applications should replace use of BN_RECP_CTX_init with BN_RECP_CTX_new
+instead:
+
+ BN_RECP_CTX *ctx;
+ ctx = BN_RECP_CTX_new();
+ if(!ctx) /* Handle error */
+ ...
+ BN_RECP_CTX_free(ctx);

=head1 HISTORY
B<BN_RECP_CTX> was added in SSLeay 0.9.0. Before that, the function
BN_reciprocal() was used instead, and the BN_mod_mul_reciprocal()
-arguments were different.
