The X509_OBJECT structure is a shallow wrapper around one X509 certificate object, one X509_CRL certificate revocation list object, one EVP_PKEY private key object, or one char * string. The type of object stored at any given time can be inspected with ().

Each X509_STORE object uses one stack of X509_OBJECT structures as its main storage area.

If obj contains an X509 certificate or an X509_CRL certificate revocation list, () increments the reference count of that inner object by 1. Otherwise, no action occurs.

If obj contains an X509 certificate, () calls X509_free(3) on that inner object. If obj contains an X509_CRL certificate revocation list, it calls X509_CRL_free(3) on that inner list. Otherwise, no action occurs. X509_OBJECT_free_contents() does not free obj itself.

If type is X509_LU_X509, () and () search the given stack for a certificate with the subject name. If type is X509_LU_CRL, they search for a certificate revocation list with the issuer name instead.

If obj contains a certificate, () searches the given stack for a certificate with a matching subject name; if it contains a certificate revocation list, it searches for a certificate revocation list with a matching issuer name instead; otherwise, it searches for an X509_OBJECT with a matching type.

X509_OBJECT_get_type() returns X509_LU_X509 if obj contains a certificate, X509_LU_CRL if it contains a certificate revocation list, or 0 if an error occurs.

X509_OBJECT_up_ref_count() returns 1 on success and 0 on failure.

X509_OBJECT_get0_X509() returns an internal pointer to the certificate contained in obj or NULL if obj is NULL or contains no certificate.

X509_OBJECT_get0_X509_CRL() returns an internal pointer to the certificate revocation list contained in obj or NULL if obj is NULL or contains no certificate revocation list.

X509_OBJECT_idx_by_subject() returns the zero-based index of the first matching certificate or revocation list in the stack or -1 if type is neither X509_LU_X509 nor X509_LU_CRL or if no match is found.

X509_OBJECT_retrieve_by_subject() returns the first matching certificate or revocation list in the stack or NULL if type is neither X509_LU_X509 nor X509_LU_CRL or if no match is found.

X509_OBJECT_retrieve_match() returns the first mathching X509_OBJECT or NULL if stack or obj is NULL or no match is found.
