.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBX509_CRL_get0_by_serial()\fR attempts to find a revoked entry in \fBcrl\fR for
serial number \fBserial\fR. If it is successful it sets \fB*ret\fR to the internal
pointer of the matching entry, as a result \fB*ret\fR must not be freed up
after the call.
.PP
\&\fBX509_CRL_get0_by_cert()\fR is similar to \fBX509_get0_by_serial()\fR except it
looks for a revoked entry using the serial number of certificate \fBx\fR.
.PP
\&\fBX509_CRL_get_REVOKED()\fR returns an internal pointer to a stack of all
revoked entries for \fBcrl\fR.
.PP
\&\fBX509_REVOKED_get0_serialNumber()\fR returns an internal pointer to the
serial number of \fBr\fR.
.PP
\&\fBX509_REVOKED_get0_revocationDate()\fR returns an internal pointer to the
revocation date of \fBr\fR.
.PP
\&\fBX509_REVOKED_set_serialNumber()\fR sets the serial number of \fBr\fR to \fBserial\fR.
The supplied \fBserial\fR pointer is not used internally so it should be
freed up after use.
.PP
\&\fBX509_REVOKED_set_revocationDate()\fR sets the revocation date of \fBr\fR to
\&\fBtm\fR. The supplied \fBtm\fR pointer is not used internally so it should be
freed up after use.
.PP
\&\fBX509_CRL_add0_revoked()\fR appends revoked entry \fBrev\fR to \s-1CRL\s0 \fBcrl\fR. The
pointer \fBrev\fR is used internally so it must not be freed up after the call:
it is freed when the parent \s-1CRL\s0 is freed.
.PP
\&\fBX509_CRL_sort()\fR sorts the revoked entries of \fBcrl\fR into ascending serial
number order.
.SH "NOTES"
.IX Header "NOTES"
Applications can determine the number of revoked entries returned by
\&\fBX509_CRL_get_revoked()\fR using \fBsk_X509_REVOKED_num()\fR and examine each one
in turn using \fBsk_X509_REVOKED_value()\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBX509_CRL_get0_by_serial()\fR and \fBX509_CRL_get0_by_cert()\fR return 0 for failure,
1 on success except if the revoked entry has the reason \f(CW\*(C`removeFromCRL\*(C'\fR (8),
in which case 2 is returned.
.PP
\&\fBX509_REVOKED_set_serialNumber()\fR, \fBX509_REVOKED_set_revocationDate()\fR,
\&\fBX509_CRL_add0_revoked()\fR and \fBX509_CRL_sort()\fR return 1 for success and 0 for
failure.
.PP
\&\fBX509_REVOKED_get0_serialNumber()\fR returns an \fB\s-1ASN1_INTEGER\s0\fR pointer.
.PP
\&\fBX509_REVOKED_get0_revocationDate()\fR returns an \fB\s-1ASN1_TIME\s0\fR value.
.PP
\&\fBX509_CRL_get_REVOKED()\fR returns a \s-1STACK\s0 of revoked entries.
