210 * This function determines how parameters are "inherited" from one structure
211 * to another. There are several different ways this can happen.
212 *
213 * 1. If a child structure needs to have its values initialized from a parent
214 * they are simply copied across. For example SSL_CTX copied to SSL.
215 * 2. If the structure should take on values only if they are currently unset.
216 * For example the values in an SSL structure will take appropriate value
217 * for SSL servers or clients but only if the application has not set new
218 * ones.
219 *
220 * The "inh_flags" field determines how this function behaves.
221 *
222 * Normally any values which are set in the default are not copied from the
223 * destination and verify flags are ORed together.
224 *
225 * If X509_VP_FLAG_DEFAULT is set then anything set in the source is copied
226 * to the destination. Effectively the values in "to" become default values
227 * which will be used only if nothing new is set in "from".
228 *
229 * If X509_VP_FLAG_OVERWRITE is set then all value are copied across whether
230 * they are set or not. Flags is still Ored though.
231 *
232 * If X509_VP_FLAG_RESET_FLAGS is set then the flags value is copied instead
233 * of ORed.
234 *
235 * If X509_VP_FLAG_LOCKED is set then no values are copied.
236 *
237 * If X509_VP_FLAG_ONCE is set then the current inh_flags setting is zeroed
238 * after the next call.
