.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBX509_CRL_get0_by_serial()\fR attempts to find a revoked entry in \fIcrl\fR for
serial number \fIserial\fR. If it is successful, it sets \fI*ret\fR to the internal
pointer of the matching entry. As a result, \fI*ret\fR \fBMUST NOT\fR be freed
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 \fIx\fR.
.PP
\&\fBX509_CRL_get_REVOKED()\fR returns an internal pointer to a STACK of all
revoked entries for \fIcrl\fR.
.PP
\&\fBX509_REVOKED_get0_serialNumber()\fR returns an internal pointer to the
serial number of \fIr\fR.
.PP
\&\fBX509_REVOKED_get0_revocationDate()\fR returns an internal pointer to the
revocation date of \fIr\fR.
.PP
\&\fBX509_REVOKED_set_serialNumber()\fR sets the serial number of \fIr\fR to \fIserial\fR.
The supplied \fIserial\fR pointer is not used internally so it should be
freed after use.
.PP
\&\fBX509_REVOKED_set_revocationDate()\fR sets the revocation date of \fIr\fR to
\&\fItm\fR. The supplied \fItm\fR pointer is not used internally so it should be
freed after use.
.PP
\&\fBX509_CRL_add0_revoked()\fR appends revoked entry \fIrev\fR to CRL \fIcrl\fR. The
pointer \fIrev\fR is used internally so it \fBMUST NOT\fR be freed after the call:
it is freed when the parent CRL is freed.
.PP
\&\fBX509_CRL_sort()\fR sorts the revoked entries of \fIcrl\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_CRL_get_REVOKED()\fR returns a STACK of revoked entries.
.PP
\&\fBX509_REVOKED_get0_serialNumber()\fR returns an \fBASN1_INTEGER\fR structure.
.PP
\&\fBX509_REVOKED_get0_revocationDate()\fR returns an \fBASN1_TIME\fR structure.
.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.
