=head1 SYNOPSIS
int DH_check(DH *dh, int *codes);
int DH_check_params(DH *dh, int *codes);
-Deprecated:
+ int DH_check_ex(const DH *dh);
+ int DH_check_params_ex(const DH *dh);
+ int DH_check_pub_key_ex(const DH *dh, const BIGNUM *pub_key);
+
+Deprecated since OpenSSL 0.9.8, can be hidden entirely by defining
+B<OPENSSL_API_COMPAT> with a suitable version value, see
+L<openssl_user_macros(7)>:
- #if OPENSSL_API_COMPAT < 0x00908000L
DH *DH_generate_parameters(int prime_len, int generator,
void (*callback)(int, int, void *), void *cb_arg);
- #endif
=head1 DESCRIPTION
=back
+DH_check_ex(), DH_check_params() and DH_check_pub_key_ex() are similar to
+DH_check() and DH_check_params() respectively, but the error reasons are added
+to the thread's error queue instead of provided as return values from the
+function.
+
=head1 RETURN VALUES
DH_generate_parameters_ex(), DH_check() and DH_check_params() return 1
DH_generate_parameters() returns a pointer to the DH structure or NULL if
the parameter generation fails.
+DH_check_ex(), DH_check_params() and DH_check_pub_key_ex() return 1 if the
+check is successful, 0 for failed.
+
The error codes can be obtained by L<ERR_get_error(3)>.
