108 | /*- |
109 | * This function determines how parameters are "inherited" from one structure | |
5d7c222d DSH |
110 | * to another. There are several different ways this can happen. |
111 | * | |
112 | * 1. If a child structure needs to have its values initialized from a parent | |
113 | * they are simply copied across. For example SSL_CTX copied to SSL. | |
114 | * 2. If the structure should take on values only if they are currently unset. | |
115 | * For example the values in an SSL structure will take appropriate value | |
116 | * for SSL servers or clients but only if the application has not set new | |
117 | * ones. | |
118 | * | |
0f113f3e | 119 | * The "inh_flags" field determines how this function behaves. |
5d7c222d DSH |
120 | * |
121 | * Normally any values which are set in the default are not copied from the | |
122 | * destination and verify flags are ORed together. | |
123 | * | |
124 | * If X509_VP_FLAG_DEFAULT is set then anything set in the source is copied | |
125 | * to the destination. Effectively the values in "to" become default values | |
126 | * which will be used only if nothing new is set in "from". | |
127 | * | |
128 | * If X509_VP_FLAG_OVERWRITE is set then all value are copied across whether | |
129 | * they are set or not. Flags is still Ored though. | |
130 | * | |
131 | * If X509_VP_FLAG_RESET_FLAGS is set then the flags value is copied instead | |
132 | * of ORed. | |
133 | * | |
134 | * If X509_VP_FLAG_LOCKED is set then no values are copied. | |
135 | * | |
136 | * If X509_VP_FLAG_ONCE is set then the current inh_flags setting is zeroed | |
137 | * after the next call. | |
