.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBX509_STORE_set1_param()\fR sets the verification parameters to \fIpm\fR for \fIxs\fR.
.PP
\&\fBX509_STORE_get0_param()\fR retrieves an internal pointer to the verification
parameters for \fIxs\fR. The returned pointer must not be freed by the
calling application
.PP
\&\fBX509_STORE_get1_objects()\fR returns a snapshot of all objects in the store\*(Aqs X509
cache. The cache contains \fBX509\fR and \fBX509_CRL\fR objects. The caller
is responsible for freeing the returned list,
using sk_X509_OBJECT_pop_free(sk, X509_OBJECT_free).
.PP
\&\fBX509_STORE_get0_objects()\fR retrieves an internal pointer to the store\*(Aqs
X509 object cache. The cache contains \fBX509\fR and \fBX509_CRL\fR objects. The
returned pointer must not be freed by the calling application. If the store is
shared across multiple threads, it is not safe to use the result of this
function. Use \fBX509_STORE_get1_objects()\fR instead, which avoids this problem.
.PP
\&\fBX509_STORE_get1_all_certs()\fR returns a list of all certificates in the store.
The caller is responsible for freeing the returned list
with \fBOSSL_STACK_OF_X509_free()\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBX509_STORE_get0_param()\fR returns a pointer to an
\&\fBX509_VERIFY_PARAM\fR structure.
.PP
\&\fBX509_STORE_set1_param()\fR returns 1 for success and 0 for failure.
.PP
\&\fBX509_STORE_get1_objects()\fR returns a pointer to a stack of the retrieved
objects on success, else NULL.
.PP
\&\fBX509_STORE_get0_objects()\fR returns a pointer to a stack of \fBX509_OBJECT\fR.
.PP
\&\fBX509_STORE_get1_all_certs()\fR returns a pointer to a stack of the retrieved
certificates on success, else NULL.
