SYNOPSIS
 #include <openssl/x509.h>

 int X509_CRL_get0_by_serial(X509_CRL *crl,
                             X509_REVOKED **ret, const ASN1_INTEGER *serial);
 int X509_CRL_get0_by_cert(X509_CRL *crl, X509_REVOKED **ret, const X509 *x);

 STACK_OF(X509_REVOKED) *X509_CRL_get_REVOKED(const X509_CRL *crl);

 const ASN1_INTEGER *X509_REVOKED_get0_serialNumber(const X509_REVOKED *r);
 const ASN1_TIME *X509_REVOKED_get0_revocationDate(const X509_REVOKED *r);

 int X509_REVOKED_set_serialNumber(X509_REVOKED *r, ASN1_INTEGER *serial);
 int X509_REVOKED_set_revocationDate(X509_REVOKED *r, ASN1_TIME *tm);

 int X509_CRL_sort(X509_CRL *crl);

DESCRIPTION
X509_CRL_get0_by_serial() attempts to find a revoked entry in crl for serial number serial. If it is successful, it sets *ret to the internal pointer of the matching entry. As a result, *ret MUST NOT be freed after the call.

X509_CRL_get0_by_cert() is similar to X509_get0_by_serial() except it looks for a revoked entry using the serial number of certificate x.

X509_CRL_get_REVOKED() returns an internal pointer to a STACK of all revoked entries for crl.

X509_REVOKED_get0_serialNumber() returns an internal pointer to the serial number of r.

X509_REVOKED_get0_revocationDate() returns an internal pointer to the revocation date of r.

X509_REVOKED_set_serialNumber() sets the serial number of r to serial. The supplied serial pointer is not used internally so it should be freed after use.

X509_REVOKED_set_revocationDate() sets the revocation date of r to tm. The supplied tm pointer is not used internally so it should be freed after use.

X509_CRL_add0_revoked() appends revoked entry rev to CRL crl. The pointer rev is used internally so it MUST NOT be freed after the call: it is freed when the parent CRL is freed.

X509_CRL_sort() sorts the revoked entries of crl into ascending serial number order.

NOTES
Applications can determine the number of revoked entries returned by X509_CRL_get_REVOKED() using sk_X509_REVOKED_num() and examine each one in turn using sk_X509_REVOKED_value().

RETURN VALUES
X509_CRL_get0_by_serial() and X509_CRL_get0_by_cert() return 0 for failure, 1 on success except if the revoked entry has the reason "removeFromCRL" (8), in which case 2 is returned.

X509_CRL_get_REVOKED() returns a STACK of revoked entries.

X509_REVOKED_get0_serialNumber() returns an ASN1_INTEGER structure.

X509_REVOKED_get0_revocationDate() returns an ASN1_TIME structure.

X509_REVOKED_set_serialNumber(), X509_REVOKED_set_revocationDate(), X509_CRL_add0_revoked() and X509_CRL_sort() return 1 for success and 0 for failure.
