DESCRIPTION

       The X509_LOOKUP_METHOD type is a structure used for the implementation of new X509_LOOKUP
       types. It provides a set of functions used by OpenSSL for the implementation of various
       X509 and X509_CRL lookup capabilities. One instance of an X509_LOOKUP_METHOD can be
       associated to many instantiations of an X509_LOOKUP structure.

       X509_LOOKUP_meth_new() creates a new X509_LOOKUP_METHOD structure. It should be given a
       human-readable string containing a brief description of the lookup method.

       X509_LOOKUP_meth_free() destroys a X509_LOOKUP_METHOD structure.

       X509_LOOKUP_get_new_item() and X509_LOOKUP_set_new_item() get and set the function that is
       called when an X509_LOOKUP object is created with X509_LOOKUP_new(). If an
       X509_LOOKUP_METHOD requires any per-X509_LOOKUP specific data, the supplied new_item
       function should allocate this data and invoke X509_LOOKUP_set_method_data().

       X509_LOOKUP_get_free() and X509_LOOKUP_set_free() get and set the function that is used to
       free any method data that was allocated and set from within new_item function.

       X509_LOOKUP_meth_get_init() and X509_LOOKUP_meth_set_init() get and set the function that
       is used to initialize the method data that was set with X509_LOOKUP_set_method_data() as
       part of the new_item routine.

       X509_LOOKUP_meth_get_shutdown() and X509_LOOKUP_meth_set_shutdown() get and set the
       function that is used to shut down the method data whose state was previously initialized
       in the init function.

       X509_LOOKUP_meth_get_ctrl() and X509_LOOKUP_meth_set_ctrl() get and set a function to be
       used to handle arbitrary control commands issued by X509_LOOKUP_ctrl(). The control
       function is given the X509_LOOKUP ctx, along with the arguments passed by
       X509_LOOKUP_ctrl. cmd is an arbitrary integer that defines some operation. argc is a
       pointer to an array of characters. argl is an integer. ret, if set, points to a location
       where any return data should be written to. How argc and argl are used depends entirely on
       the control function.

       X509_LOOKUP_set_get_by_subject(), X509_LOOKUP_set_get_by_issuer_serial(),
       X509_LOOKUP_set_get_by_fingerprint(), X509_LOOKUP_set_get_by_alias() set the functions
       used to retrieve an X509 or X509_CRL object by the object's subject, issuer, fingerprint,
       and alias respectively. These functions are given the X509_LOOKUP context, the type of the
       X509_OBJECT being requested, parameters related to the lookup, and an X509_OBJECT that
       will receive the requested object.

       Implementations should use either X509_OBJECT_set1_X509() or X509_OBJECT_set1_X509_CRL()
       to set the result. Any method data that was created as a result of the new_item function
       set by X509_LOOKUP_meth_set_new_item() can be accessed with X509_LOOKUP_get_method_data().
       The X509_STORE object that owns the X509_LOOKUP may be accessed with
       X509_LOOKUP_get_store(). Successful lookups should return 1, and unsuccessful lookups
       should return 0.

       X509_LOOKUP_get_get_by_subject(), X509_LOOKUP_get_get_by_issuer_serial(),
       X509_LOOKUP_get_get_by_fingerprint(), X509_LOOKUP_get_get_by_alias() retrieve the function
       set by the corresponding setter.

RETURN VALUES

       The X509_LOOKUP_meth_set functions return 1 on success or 0 on error.

       The X509_LOOKUP_meth_get functions return the corresponding function pointers.
