105/* This function determines how parameters are "inherited" from one structure
106 * to another. There are several different ways this can happen.
107 *
108 * 1. If a child structure needs to have its values initialized from a parent
109 * they are simply copied across. For example SSL_CTX copied to SSL.
110 * 2. If the structure should take on values only if they are currently unset.
111 * For example the values in an SSL structure will take appropriate value
112 * for SSL servers or clients but only if the application has not set new
113 * ones.
114 *
115 * The "inh_flags" field determines how this function behaves.
116 *
117 * Normally any values which are set in the default are not copied from the
118 * destination and verify flags are ORed together.
119 *
120 * If X509_VP_FLAG_DEFAULT is set then anything set in the source is copied
121 * to the destination. Effectively the values in "to" become default values
122 * which will be used only if nothing new is set in "from".
123 *
124 * If X509_VP_FLAG_OVERWRITE is set then all value are copied across whether
125 * they are set or not. Flags is still Ored though.
126 *
127 * If X509_VP_FLAG_RESET_FLAGS is set then the flags value is copied instead
128 * of ORed.
129 *
130 * If X509_VP_FLAG_LOCKED is set then no values are copied.
131 *
132 * If X509_VP_FLAG_ONCE is set then the current inh_flags setting is zeroed
133 * after the next call.
