+ * This function determines how parameters are "inherited" from one structure
+ * to another. There are several different ways this can happen.
+ *
+ * 1. If a child structure needs to have its values initialized from a parent
+ * they are simply copied across. For example SSL_CTX copied to SSL.
+ * 2. If the structure should take on values only if they are currently unset.
+ * For example the values in an SSL structure will take appropriate value
+ * for SSL servers or clients but only if the application has not set new
+ * ones.
+ *
+ * The "inh_flags" field determines how this function behaves.
+ *
+ * Normally any values which are set in the default are not copied from the
+ * destination and verify flags are ORed together.
+ *
+ * If X509_VP_FLAG_DEFAULT is set then anything set in the source is copied
+ * to the destination. Effectively the values in "to" become default values
+ * which will be used only if nothing new is set in "from".
+ *
+ * If X509_VP_FLAG_OVERWRITE is set then all value are copied across whether
+ * they are set or not. Flags is still Ored though.
+ *
+ * If X509_VP_FLAG_RESET_FLAGS is set then the flags value is copied instead
+ * of ORed.
+ *
+ * If X509_VP_FLAG_LOCKED is set then no values are copied.
+ *
+ * If X509_VP_FLAG_ONCE is set then the current inh_flags setting is zeroed
+ * after the next call.
