.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fIX509_get0_notBefore()\fR and \fIX509_get0_notAfter()\fR return the \fBnotBefore\fR
and \fBnotAfter\fR fields of certificate \fBx\fR respectively. The value
returned is an internal pointer which must not be freed up after
the call.
.PP
\&\fIX509_getm_notBefore()\fR and \fIX509_getm_notAfter()\fR are similar to
\&\fIX509_get0_notBefore()\fR and \fIX509_get0_notAfter()\fR except they return
non-constant mutable references to the associated date field of
the certificate.
.PP
\&\fIX509_set1_notBefore()\fR and \fIX509_set1_notAfter()\fR set the \fBnotBefore\fR
and \fBnotAfter\fR fields of \fBx\fR to \fBtm\fR. Ownership of the passed
parameter \fBtm\fR is not transferred by these functions so it must
be freed up after the call.
.PP
\&\fIX509_CRL_get0_lastUpdate()\fR and \fIX509_CRL_get0_nextUpdate()\fR return the
\&\fBlastUpdate\fR and \fBnextUpdate\fR fields of \fBcrl\fR. The value
returned is an internal pointer which must not be freed up after
the call. If the \fBnextUpdate\fR field is absent from \fBcrl\fR then
\&\fB\s-1NULL\s0\fR is returned.
.PP
\&\fIX509_CRL_set1_lastUpdate()\fR and \fIX509_CRL_set1_nextUpdate()\fR set the \fBlastUpdate\fR
and \fBnextUpdate\fR fields of \fBcrl\fR to \fBtm\fR. Ownership of the passed parameter
\&\fBtm\fR is not transferred by these functions so it must be freed up after the
call.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fIX509_get0_notBefore()\fR, \fIX509_get0_notAfter()\fR and \fIX509_CRL_get0_lastUpdate()\fR
return a pointer to an \fB\s-1ASN1_TIME\s0\fR structure.
.PP
\&\fIX509_CRL_get0_lastUpdate()\fR return a pointer to an \fB\s-1ASN1_TIME\s0\fR structure
or \s-1NULL\s0 if the \fBlastUpdate\fR field is absent.
.PP
\&\fIX509_set1_notBefore()\fR, \fIX509_set1_notAfter()\fR, \fIX509_CRL_set1_lastUpdate()\fR and
\&\fIX509_CRL_set1_nextUpdate()\fR return 1 for success or 0 for failure.
