# NAME

# SYNOPSIS

     #include <openssl/x509_vfy.h>
     X509_STORE *X509_STORE_new(void);
     void X509_STORE_free(X509_STORE *xs);
     int X509_STORE_lock(X509_STORE *xs);
     int X509_STORE_unlock(X509_STORE *xs);
     int X509_STORE_up_ref(X509_STORE *xs);

# DESCRIPTION

The X509_STORE_new() function returns a new X509_STORE.

X509_STORE_up_ref() increments the reference count associated with the X509_STORE object.

X509_STORE_lock() locks the store from modification by other threads, X509_STORE_unlock() unlocks it.

X509_STORE_free() frees up a single X509_STORE object. If the argument is NULL, nothing is done.

# RETURN VALUES

X509_STORE_new() returns a newly created X509_STORE or NULL if the call fails.

X509_STORE_up_ref(), X509_STORE_lock() and X509_STORE_unlock() return 1 for success and 0 for failure.

X509_STORE_free() does not return values.
