=head1 NAME

X509_STORE_get0_param, X509_STORE_set1_param,
X509_STORE_get0_objects, X509_STORE_get1_all_certs
- X509_STORE setter and getter functions

=head1 SYNOPSIS

 #include <openssl/x509_vfy.h>

 X509_VERIFY_PARAM *X509_STORE_get0_param(const X509_STORE *xs);
 int X509_STORE_set1_param(X509_STORE *xs, const X509_VERIFY_PARAM *pm);
 STACK_OF(X509_OBJECT) *X509_STORE_get0_objects(const X509_STORE *xs);
 STACK_OF(X509) *X509_STORE_get1_all_certs(X509_STORE *xs);

=head1 DESCRIPTION

X509_STORE_set1_param() sets the verification parameters to I<pm> for I<xs>.

X509_STORE_get0_param() retrieves an internal pointer to the verification
parameters for I<xs>. The returned pointer must not be freed by the
calling application

X509_STORE_get0_objects() retrieves an internal pointer to the store's
X509 object cache. The cache contains B<X509> and B<X509_CRL> objects. The
returned pointer must not be freed by the calling application.

X509_STORE_get1_all_certs() returns a list of all certificates in the store.
The caller is responsible for freeing the returned list.

=head1 RETURN VALUES

X509_STORE_get0_param() returns a pointer to an
B<X509_VERIFY_PARAM> structure.

X509_STORE_set1_param() returns 1 for success and 0 for failure.

X509_STORE_get0_objects() returns a pointer to a stack of B<X509_OBJECT>.

X509_STORE_get1_all_certs() returns a pointer to a stack of the retrieved
certificates on success, else NULL.
