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