\&\fBX509_LOOKUP_shutdown()\fR tears down the internal state and resources of
the given \fBX509_LOOKUP\fR.
.PP
\&\fBX509_LOOKUP_free()\fR destructs the given \fBX509_LOOKUP\fR.
.PP
\&\fBX509_LOOKUP_set_method_data()\fR associates a pointer to application data
to the given \fBX509_LOOKUP\fR.
.PP
\&\fBX509_LOOKUP_get_method_data()\fR retrieves a pointer to application data
from the given \fBX509_LOOKUP\fR.
.PP
\&\fBX509_LOOKUP_ctrl()\fR is used to set or get additional data to or from an
\&\fBX509_LOOKUP\fR structure or its associated \fBX509_LOOKUP_METHOD\fR\|(3).
The arguments of the control command are passed via \fIargc\fR and \fIargl\fR,
its return value via \fI*ret\fR.
The meaning of the arguments depends on the \fIcmd\fR number of the
control command. In general, this function is not called directly, but
wrapped by a macro call, see below.
The control \fIcmd\fRs known to OpenSSL are discussed in more depth
in \*(L"Control Commands\*(R".
.PP
\&\fBX509_LOOKUP_load_file()\fR passes a filename to be loaded immediately
into the associated \fBX509_STORE\fR.
\&\fItype\fR indicates what type of object is expected.
This can only be used with a lookup using the implementation
\&\fBX509_LOOKUP_file\fR\|(3).
.PP
\&\fBX509_LOOKUP_add_dir()\fR passes a directory specification from which
certificates and CRLs are loaded on demand into the associated
\&\fBX509_STORE\fR.
\&\fItype\fR indicates what type of object is expected.
This can only be used with a lookup using the implementation
\&\fBX509_LOOKUP_hash_dir\fR\|(3).
.PP
\&\fBX509_LOOKUP_load_file()\fR, \fBX509_LOOKUP_add_dir()\fR,
\&\fBX509_LOOKUP_add_store()\fR, and \fBX509_LOOKUP_load_store()\fR are implemented
as macros that use \fBX509_LOOKUP_ctrl()\fR.
.PP
\&\fBX509_LOOKUP_by_subject()\fR, \fBX509_LOOKUP_by_issuer_serial()\fR,
\&\fBX509_LOOKUP_by_fingerprint()\fR, and \fBX509_LOOKUP_by_alias()\fR look up
certificates and CRLs in the \fBX509_STORE\fR\|(3) associated with the
\&\fBX509_LOOKUP\fR using different criteria, where the looked up object is
stored in \fIret\fR.
Some of the underlying \fBX509_LOOKUP_METHOD\fRs will also cache objects
matching the criteria in the associated \fBX509_STORE\fR, which makes it
possible to handle cases where the criteria have more than one hit.
.SS "File Types"
.IX Subsection "File Types"
\&\fBX509_LOOKUP_load_file()\fR and \fBX509_LOOKUP_add_dir()\fR take a \fItype\fR,
which can be one of the following:
.IP "\fBX509_FILETYPE_PEM\fR" 4
.IX Item "X509_FILETYPE_PEM"
The file or files that are loaded are expected to be in \s-1PEM\s0 format.
.IP "\fBX509_FILETYPE_ASN1\fR" 4
.IX Item "X509_FILETYPE_ASN1"
The file or files that are loaded are expected to be in raw \s-1DER\s0 format.
.IP "\fBX509_FILETYPE_DEFAULT\fR" 4
.IX Item "X509_FILETYPE_DEFAULT"
The default certificate file or directory is used.  In this case,
\&\fIname\fR is ignored.
.SS "Control Commands"
.IX Subsection "Control Commands"
The \fBX509_LOOKUP_METHOD\fRs built into OpenSSL recognise the following
\&\fBX509_LOOKUP_ctrl()\fR \fIcmd\fRs:
.IP "\fBX509_L_FILE_LOAD\fR" 4
.IX Item "X509_L_FILE_LOAD"
This is the command that \fBX509_LOOKUP_load_file()\fR uses.
The filename is passed in \fIargc\fR, and the type in \fIargl\fR.
.IP "\fBX509_L_ADD_DIR\fR" 4
.IX Item "X509_L_ADD_DIR"
This is the command that \fBX509_LOOKUP_add_dir()\fR uses.
The directory specification is passed in \fIargc\fR, and the type in
\&\fIargl\fR.
.IP "\fBX509_L_ADD_STORE\fR" 4
.IX Item "X509_L_ADD_STORE"
This is the command that \fBX509_LOOKUP_add_store()\fR uses.
The \s-1URI\s0 is passed in \fIargc\fR.
.IP "\fBX509_L_LOAD_STORE\fR" 4
.IX Item "X509_L_LOAD_STORE"
This is the command that \fBX509_LOOKUP_load_store()\fR uses.
The \s-1URI\s0 is passed in \fIargc\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBX509_LOOKUP_new()\fR returns an \fBX509_LOOKUP\fR pointer when successful,
or \s-1NULL\s0 on error.
.PP
\&\fBX509_LOOKUP_init()\fR and \fBX509_LOOKUP_shutdown()\fR return 1 on success, or
0 on error.
.PP
\&\fBX509_LOOKUP_ctrl()\fR returns \-1 if the \fBX509_LOOKUP\fR doesn't have an
associated \fBX509_LOOKUP_METHOD\fR, or 1 if the 
doesn't have a control function.
Otherwise, it returns what the control function in the
\&\fBX509_LOOKUP_METHOD\fR returns, which is usually 1 on success and 0 in
error.
.IX Xref "509_LOOKUP_METHOD"
.PP
\&\fBX509_LOOKUP_get_store()\fR returns an \fBX509_STORE\fR pointer if there is
one, otherwise \s-1NULL.\s0
.PP
\&\fBX509_LOOKUP_by_subject()\fR, \fBX509_LOOKUP_by_issuer_serial()\fR,
\&\fBX509_LOOKUP_by_fingerprint()\fR, and \fBX509_LOOKUP_by_alias()\fR all return 0
if there is no \fBX509_LOOKUP_METHOD\fR or that method doesn't implement
the corresponding function.
Otherwise, it returns what the corresponding function in the
\&\fBX509_LOOKUP_METHOD\fR returns, which is usually 1 on success and 0 in
error.
