/*-

 * The error code packs differently depending on if it records a system

 * error or an OpenSSL error.

 *

 * A system error packs like this (we follow POSIX and only allow positive

 * numbers that fit in an |int|):

 *

 * +-+-------------------------------------------------------------+

 * |1|                     system error number                     |

 * +-+-------------------------------------------------------------+

 *

 * An OpenSSL error packs like this:

 *

 * <---------------------------- 32 bits -------------------------->

 *    <--- 8 bits ---><------------------ 23 bits ----------------->

 * +-+---------------+---------------------------------------------+

 * |0|    library    |                    reason                   |

 * +-+---------------+---------------------------------------------+

 *

 * A few of the reason bits are reserved as flags with special meaning:

 *

 *                    <5 bits-<>--------- 19 bits ----------------->

 *                   +-------+-+-----------------------------------+

 *                   | rflags| |          reason                   |

 *                   +-------+-+-----------------------------------+

 *                            ^

 *                            |

 *                           ERR_RFLAG_FATAL = ERR_R_FATAL

 *

 * The reason flags are part of the overall reason code for practical

 * reasons, as they provide an easy way to place different types of

 * reason codes in different numeric ranges.

 *

 * The currently known reason flags are:

 *

 * ERR_RFLAG_FATAL      Flags that the reason code is considered fatal.

 *                      For backward compatibility reasons, this flag

 *                      is also the code for ERR_R_FATAL (that reason

 *                      code served the dual purpose of flag and reason

 *                      code in one in pre-3.0 OpenSSL).

 * ERR_RFLAG_COMMON     Flags that the reason code is common to all

 *                      libraries.  All ERR_R_ macros must use this flag,

 *                      and no other _R_ macro is allowed to use it.
