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(3) 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. If
the argument is NULL, nothing is done.
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(3).
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(3) 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 must add objects they find to the X509_STORE object
using X509_STORE_add_cert() or X509_STORE_add_crl(). This increments
its reference count. However, the X509_STORE_CTX_get_by_subject(3)
function also increases the reference count which leads to one too many
references being held. Therefore, applications should additionally
call X509_free() or X509_CRL_free() to decrement the reference count
again.
Implementations should also use either X509_OBJECT_set1_X509() or
X509_OBJECT_set1_X509_CRL() to set the result. Note that this also
increments the result's reference count.
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(3). The X509_STORE object that owns the
X509_LOOKUP may be accessed with X509_LOOKUP_get_store(3). 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.
