# NAME

X509_STORE_get0_param, X509_STORE_set1_param, X509_STORE_get1_objects, X509_STORE_get0_objects, X509_STORE_get1_all_certs - X509_STORE setter and getter functions

# 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_get1_objects(X509_STORE *xs);
     STACK_OF(X509_OBJECT) *X509_STORE_get0_objects(const X509_STORE *xs);
     STACK_OF(X509) *X509_STORE_get1_all_certs(X509_STORE *xs);

# DESCRIPTION

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

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

X509_STORE_get1_objects() returns a snapshot of all objects in the store's X509 cache. The cache contains X509 and X509_CRL objects. The caller is responsible for freeing the returned list, using sk_X509_OBJECT_pop_free(sk, X509_OBJECT_free).

X509_STORE_get0_objects() retrieves an internal pointer to the store's X509 object cache. The cache contains X509 and X509_CRL 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 X509_STORE_get1_objects() instead, which avoids this problem.

X509_STORE_get1_all_certs() returns a list of all certificates in the store. The caller is responsible for freeing the returned list with OSSL_STACK_OF_X509_free().

# RETURN VALUES

X509_STORE_get0_param() returns a pointer to an X509_VERIFY_PARAM structure.

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

X509_STORE_get1_objects() returns a pointer to a stack of the retrieved objects on success, else NULL.

X509_STORE_get0_objects() returns a pointer to a stack of X509_OBJECT.

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