DESCRIPTION
X509_CRL_new
()
allocates and initializes an empty X509_CRL object,
representing an ASN.1 CertificateList structure
defined in RFC 5280 section 5.1. It can hold a pointer to an
X509_CRL_INFO object discussed below together with a
cryptographic signature and information about the signature algorithm used.
The reference count is set to 1.
X509_CRL_dup
()
creates a deep copy of crl.
X509_CRL_up_ref
()
increments the reference count of crl by 1.
X509_CRL_free
()
decrements the reference count of crl by 1. If the
reference count reaches 0, it frees crl. If
X509_CRL_set_default_method(3) was in effect at the time
crl was created and the
crl_free
()
callback is not NULL
, that callback is invoked near
the end of X509_CRL_free
(), right before freeing
crl itself.
X509_CRL_INFO_new
()
allocates and initializes an empty X509_CRL_INFO
object, representing an ASN.1 TBSCertList structure
defined in RFC 5280 section 5.1. It is used inside the
X509_CRL object and can hold a list of revoked
certificates, an issuer name, the time the list was issued, the time when
the next update of the list is due, and optional extensions.
X509_CRL_INFO_free
()
frees crl_info.
RETURN VALUES
X509_CRL_new
(),
X509_CRL_dup
(), and
X509_CRL_INFO_new
() return the new
X509_CRL or X509_CRL_INFO
object, respectively, or NULL
if an error
occurs.
X509_CRL_up_ref
() returns 1 on success or
0 on error.
