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. Consequently, *ret must not be freed up after the call.

X509_CRL_get0_by_cert() is similar to X509_CRL_get0_by_serial() except that 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. It is implemented as a macro.

X509_CRL_add0_revoked() appends revoked entry rev to CRL crl. The pointer rev is used internally so it must not be freed up 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.

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(), both defined in <openssl/safestack.h>.

X509_CRL_get0_by_serial() and X509_CRL_get0_by_cert() return 0 for failure or 1 for success, except if the revoked entry has the reason “removeFromCRL”, in which case 2 is returned.

The X509_CRL_add0_revoked() function returns 1 if successful; otherwise 0 is returned and an error code can be retrieved with ERR_get_error(3).

X509_CRL_sort() returns 1 for success or 0 for failure. The current implementation cannot fail.

X509_CRL_get_REVOKED() returns a STACK of revoked entries.
