173 * The error code packs differently depending on if it records a system
174 * error or an OpenSSL error.
175 *
176 * A system error packs like this (we follow POSIX and only allow positive
177 * numbers that fit in an |int|):
178 *
179 * +-+-------------------------------------------------------------+
180 * |1| system error number |
181 * +-+-------------------------------------------------------------+
182 *
183 * An OpenSSL error packs like this:
184 *
185 * <---------------------------- 32 bits -------------------------->
186 * <--- 8 bits ---><------------------ 23 bits ----------------->
187 * +-+---------------+---------------------------------------------+
188 * |0| library | reason |
189 * +-+---------------+---------------------------------------------+
190 *
191 * A few of the reason bits are reserved as flags with special meaning:
192 *
193 * <5 bits-<>--------- 19 bits ----------------->
194 * +-------+-+-----------------------------------+
195 * | rflags| | reason |
196 * +-------+-+-----------------------------------+
197 * ^
198 * |
199 * ERR_RFLAG_FATAL = ERR_R_FATAL
200 *
201 * The reason flags are part of the overall reason code for practical
202 * reasons, as they provide an easy way to place different types of
203 * reason codes in different numeric ranges.
204 *
205 * The currently known reason flags are:
206 *
207 * ERR_RFLAG_FATAL Flags that the reason code is considered fatal.
208 * For backward compatibility reasons, this flag
209 * is also the code for ERR_R_FATAL (that reason
210 * code served the dual purpose of flag and reason
211 * code in one in pre-3.0 OpenSSL).
212 * ERR_RFLAG_COMMON Flags that the reason code is common to all
213 * libraries. All ERR_R_ macros must use this flag,
214 * and no other _R_ macro is allowed to use it.
