NAME
     ENGINE_unregister_RSA, ENGINE_unregister_DSA, ENGINE_unregister_ECDH,
     ENGINE_unregister_ECDSA, ENGINE_unregister_DH, ENGINE_unregister_RAND,
     ENGINE_unregister_STORE, ENGINE_unregister_ciphers,
     ENGINE_unregister_digests -- revoke the registration of an ENGINE object

SYNOPSIS
     #include <openssl/engine.h>

     void
     ENGINE_unregister_RSA(ENGINE *e);

     void
     ENGINE_unregister_DSA(ENGINE *e);

     void
     ENGINE_unregister_ECDH(ENGINE *e);

     void
     ENGINE_unregister_ECDSA(ENGINE *e);

     void
     ENGINE_unregister_DH(ENGINE *e);

     void
     ENGINE_unregister_RAND(ENGINE *e);

     void
     ENGINE_unregister_STORE(ENGINE *e);

     void
     ENGINE_unregister_ciphers(ENGINE *e);

     void
     ENGINE_unregister_digests(ENGINE *e);

DESCRIPTION
     These functions remove e from the list of ENGINE objects that were previ-
     ously registered for the respective algorithm with the functions
     described in ENGINE_register_RSA(3).

     If e is currently used as the default engine for the algorithm as
     described in the ENGINE_set_default(3) and ENGINE_get_default_RSA(3) man-
     ual pages, ENGINE_finish(3) is also called.

     ENGINE_unregister_ciphers() and ENGINE_unregister_digests() unregister e
     for all ciphers or digests, respectively.

     ENGINE_register_RSA(3), ENGINE_set_default(3)

HISTORY
     ENGINE_unregister_RSA(), ENGINE_unregister_DSA(), ENGINE_unregister_DH(),
     ENGINE_unregister_RAND(), ENGINE_unregister_ciphers(), and
     ENGINE_unregister_digests() first appeared in OpenSSL 0.9.7 and have been
     available since OpenBSD 3.2.

     ENGINE_unregister_ECDH(), ENGINE_unregister_ECDSA(), and
     ENGINE_unregister_STORE() first appeared in OpenSSL 0.9.8 and have been
     available since OpenBSD 4.5.
