.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBX509_LOOKUP_METHOD\fR 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
\&\fBX509_LOOKUP\fR structure.
.PP
\&\fIX509_LOOKUP_meth_new()\fR creates a new \fBX509_LOOKUP_METHOD\fR structure. It should
be given a human-readable string containing a brief description of the lookup
method.
.PP
\&\fIX509_LOOKUP_meth_free()\fR destroys a \fBX509_LOOKUP_METHOD\fR structure.
.PP
\&\fIX509_LOOKUP_get_new_item()\fR and \fIX509_LOOKUP_set_new_item()\fR get and set the
function that is called when an \fBX509_LOOKUP\fR object is created with
\&\fIX509_LOOKUP_new()\fR. If an X509_LOOKUP_METHOD requires any per\-X509_LOOKUP
specific data, the supplied new_item function should allocate this data and
invoke \fIX509_LOOKUP_set_method_data\fR\|(3).
.PP
\&\fIX509_LOOKUP_get_free()\fR and \fIX509_LOOKUP_set_free()\fR get and set the function
that is used to free any method data that was allocated and set from within
new_item function.
.PP
\&\fIX509_LOOKUP_meth_get_init()\fR and \fIX509_LOOKUP_meth_set_init()\fR get and set the
function that is used to initialize the method data that was set with
\&\fIX509_LOOKUP_set_method_data\fR\|(3) as part of the new_item routine.
.PP
\&\fIX509_LOOKUP_meth_get_shutdown()\fR and \fIX509_LOOKUP_meth_set_shutdown()\fR get and set
the function that is used to shut down the method data whose state was
previously initialized in the init function.
.PP
\&\fIX509_LOOKUP_meth_get_ctrl()\fR and \fIX509_LOOKUP_meth_set_ctrl()\fR get and set a
function to be used to handle arbitrary control commands issued by
\&\fIX509_LOOKUP_ctrl()\fR. The control function is given the X509_LOOKUP
\&\fBctx\fR, along with the arguments passed by X509_LOOKUP_ctrl. \fBcmd\fR is
an arbitrary integer that defines some operation. \fBargc\fR is a pointer
to an array of characters. \fBargl\fR is an integer. \fBret\fR, if set,
points to a location where any return data should be written to. How
\&\fBargc\fR and \fBargl\fR are used depends entirely on the control function.
.PP
\&\fIX509_LOOKUP_set_get_by_subject()\fR, \fIX509_LOOKUP_set_get_by_issuer_serial()\fR,
\&\fIX509_LOOKUP_set_get_by_fingerprint()\fR, \fIX509_LOOKUP_set_get_by_alias()\fR 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.
.PP
Implementations must add objects they find to the \fBX509_STORE\fR object
using \fIX509_STORE_add_cert()\fR or \fIX509_STORE_add_crl()\fR. This increments
its reference count. However, the \fIX509_STORE_CTX_get_by_subject()\fR
function also increases the reference count which leads to one too
many references being held. Therefore, applications should
additionally call \fIX509_free()\fR or \fIX509_CRL_free()\fR to decrement the
reference count again.
.PP
Implementations should also use either \fIX509_OBJECT_set1_X509()\fR or
\&\fIX509_OBJECT_set1_X509_CRL()\fR to set the result. Note that this also
increments the result's reference count.
.PP
Any method data that was created as a result of the new_item function
set by \fIX509_LOOKUP_meth_set_new_item()\fR can be accessed with
\&\fIX509_LOOKUP_get_method_data\fR\|(3). The \fBX509_STORE\fR object that owns the
X509_LOOKUP may be accessed with \fIX509_LOOKUP_get_store\fR\|(3). Successful
lookups should return 1, and unsuccessful lookups should return 0.
.PP
\&\fIX509_LOOKUP_get_get_by_subject()\fR, \fIX509_LOOKUP_get_get_by_issuer_serial()\fR,
\&\fIX509_LOOKUP_get_get_by_fingerprint()\fR, \fIX509_LOOKUP_get_get_by_alias()\fR retrieve
the function set by the corresponding setter.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
The \fBX509_LOOKUP_meth_set\fR functions return 1 on success or 0 on error.
.PP
The \fBX509_LOOKUP_meth_get\fR functions return the corresponding function
pointers.
