() 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.

() creates a deep copy of crl.

() increments the reference count of crl by 1.

() decrements the reference count of crl by 1. If the reference count reaches 0, it frees crl.

() 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. () frees crl_info.

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.
