106 The X509_LOOKUP_METHOD type is a structure used for the implementation
107 of new X509_LOOKUP types. It provides a set of functions used by
108 OpenSSL for the implementation of various X509 and X509_CRL lookup
109 capabilities. One instance of an X509_LOOKUP_METHOD can be associated
110 to many instantiations of an X509_LOOKUP structure.
111 X509_LOOKUP_meth_new() creates a new X509_LOOKUP_METHOD structure. It
113 should be given a human-readable string containing a brief description
114 of the lookup method.
115 X509_LOOKUP_meth_free() destroys a X509_LOOKUP_METHOD structure.
117 X509_LOOKUP_get_new_item() and X509_LOOKUP_set_new_item() get and set
119 the function that is called when an X509_LOOKUP object is created with
120 X509_LOOKUP_new(). If an X509_LOOKUP_METHOD requires any
121 per-X509_LOOKUP specific data, the supplied new_item function should
122 allocate this data and invoke X509_LOOKUP_set_method_data().
123 X509_LOOKUP_get_free() and X509_LOOKUP_set_free() get and set the
125 function that is used to free any method data that was allocated and
126 set from within new_item function.
127 X509_LOOKUP_meth_get_init() and X509_LOOKUP_meth_set_init() get and set
129 the function that is used to initialize the method data that was set
130 with X509_LOOKUP_set_method_data() as part of the new_item routine.
131 X509_LOOKUP_meth_get_shutdown() and X509_LOOKUP_meth_set_shutdown() get
133 and set the function that is used to shut down the method data whose
134 state was previously initialized in the init function.
135 X509_LOOKUP_meth_get_ctrl() and X509_LOOKUP_meth_set_ctrl() get and set
137 a function to be used to handle arbitrary control commands issued by
138 X509_LOOKUP_ctrl(). The control function is given the X509_LOOKUP ctx,
139 along with the arguments passed by X509_LOOKUP_ctrl. cmd is an
140 arbitrary integer that defines some operation. argc is a pointer to an
141 array of characters. argl is an integer. ret, if set, points to a
142 location where any return data should be written to. How argc and argl
143 are used depends entirely on the control function.
144 X509_LOOKUP_set_get_by_subject(),
146 X509_LOOKUP_set_get_by_issuer_serial(),
147 X509_LOOKUP_set_get_by_fingerprint(), X509_LOOKUP_set_get_by_alias()
148 set the functions used to retrieve an X509 or X509_CRL object by the
149 object's subject, issuer, fingerprint, and alias respectively. These
150 functions are given the X509_LOOKUP context, the type of the
151 X509_OBJECT being requested, parameters related to the lookup, and an
152 X509_OBJECT that will receive the requested object.
153 Implementations should use either X509_OBJECT_set1_X509() or
155 X509_OBJECT_set1_X509_CRL() to set the result. Any method data that was
156 created as a result of the new_item function set by
157 X509_LOOKUP_meth_set_new_item() can be accessed with
158 X509_LOOKUP_get_method_data(). The X509_STORE object that owns the
159 X509_LOOKUP may be accessed with X509_LOOKUP_get_store(). Successful
160 lookups should return 1, and unsuccessful lookups should return 0.
161 X509_LOOKUP_get_get_by_subject(),
163 X509_LOOKUP_get_get_by_issuer_serial(),
164 X509_LOOKUP_get_get_by_fingerprint(), X509_LOOKUP_get_get_by_alias()
165 retrieve the function set by the corresponding setter.
166
168 The X509_LOOKUP_meth_set functions return 1 on success or 0 on error.
169 The X509_LOOKUP_meth_get functions return the corresponding function
171 pointers.
