The value 33returned is an internal pointer which must not be freed up after 34the call. 35 36X509_getm_notBefore() and X509_getm_notAfter() are similar to 37X509_get0_notBefore() and X509_get0_notAfter() except they return 38non-constant mutable references to the associated date field of 39the certificate. 40 41X509_set1_notBefore() and X509_set1_notAfter() set the B<notBefore> 42and B<notAfter> fields of B<x> to B<tm>. Ownership of the passed 43parameter B<tm> is not transferred by these functions so it must 44be freed up after the call. 45 46X509_CRL_get0_lastUpdate() and X509_CRL_get0_nextUpdate() return the 47B<lastUpdate> and B<nextUpdate> fields of B<crl>. The value 48returned is an internal pointer which must not be freed up after 49the call. If the B<nextUpdate> field is absent from B<crl> then 50B<NULL> is returned. 51 52X509_CRL_set1_lastUpdate() and X509_CRL_set1_nextUpdate() set the B<lastUpdate> 53and B<nextUpdate> fields of B<crl> to B<tm>. Ownership of the passed parameter 54B<tm> is not transferred by these functions so it must be freed up after the 55call. 56 57=head1 RETURN VALUES 58 59X509_get0_notBefore(), X509_get0_notAfter() and X509_CRL_get0_lastUpdate() 60return a pointer to an B<ASN1_TIME> structure. 61 62X509_CRL_get0_lastUpdate() return a pointer to an B<ASN1_TIME> structure 63or NULL if the B<lastUpdate> field is absent. 64 65X509_set1_notBefore(), X509_set1_notAfter(), X509_CRL_set1_lastUpdate() and 66X509_CRL_set1_nextUpdate() return 1 for success or 0 for failure. 67 68=head1 SEE ALSO 69 70L<d2i_X509(3)>, 71L<ERR_get_error(3)>, 72L<X509_CRL_get0_by_serial(3)>, 73L<X509_get0_signature(3)>, 74L<X509_get_ext_d2i(3)>, 75L<X509_get_extension_flags(3)>, 76L<X509_get_pubkey(3)>, 77L<X509_get_subject_name(3)>, 78L<X509_NAME_add_entry_by_txt(3)>, 79L<X509_NAME_ENTRY_get_object(3)>, 80L<X509_NAME_get_index_by_NID(3)>, 81L<X509_NAME_print_ex(3)>, 82L<X509_new(3)>, 83L<X509_sign(3)>, 84L<X509V3_get_d2i(3)>, 85L<X509_verify_cert(3)> 86 87=head1 HISTORY 88 89These functions are available in all versions of OpenSSL. 90 91X509_get_notBefore() and X509_get_notAfter() were deprecated in OpenSSL 921.1.0 93 94=head1 COPYRIGHT 95 96Copyright 2016 The OpenSSL Project Authors.
