.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBOSSL_STORE_expect()\fR helps applications filter what \fBOSSL_STORE_load()\fR returns
by specifying a \fB\s-1OSSL_STORE_INFO\s0\fR type.
For example, if \f(CW\*(C`file:/foo/bar/store.pem\*(C'\fR contains several different objects
and only the certificates are interesting, the application can simply say
that it expects the type \fB\s-1OSSL_STORE_INFO_CERT\s0\fR.
All known object types (see \*(L"\s-1SUPPORTED OBJECTS\*(R"\s0 in \s-1\fBOSSL_STORE_INFO\s0\fR\|(3))
except for \fB\s-1OSSL_STORE_INFO_NAME\s0\fR are supported.
.PP
\&\fBOSSL_STORE_find()\fR helps applications specify a criterion for a more fine
grained search of objects.
.PP
\&\fBOSSL_STORE_supports_search()\fR checks if the loader of the given \s-1OSSL_STORE\s0
context supports the given search type.
See \*(L"\s-1SUPPORTED CRITERION TYPES\*(R"\s0 in \s-1OSSL_STORE_SEARCH\s0 for information on the
supported search criterion types.
.PP
\&\fBOSSL_STORE_expect()\fR and OSSL_STORE_find \fImust\fR be called before the first
\&\fBOSSL_STORE_load()\fR of a given session, or they will fail.
.SH "NOTES"
.IX Header "NOTES"
If a more elaborate filter is required by the application, a better choice
would be to use a post-processing function.
See \fBOSSL_STORE_open\fR\|(3) for more information.
.PP
However, some loaders may take advantage of the knowledge of an expected type
to make object retrieval more efficient, so if a single type is expected, this
method is usually preferable.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBOSSL_STORE_expect()\fR returns 1 on success, or 0 on failure.
.PP
\&\fBOSSL_STORE_supports_search()\fR returns 1 if the criterion is supported, or 0
otherwise.
.PP
\&\fBOSSL_STORE_find()\fR returns 1 on success, or 0 on failure.
