-/* 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.
