/* Error queue handling functions.
*
* Errors in OpenSSL are generally signalled by the return value of a function.
* When a function fails it may add an entry to a per-thread error queue,
* which is managed by the functions in this header.
*
* Each error contains:
* 1) The library (i.e. ec, pem, rsa) which created it.
* 2) A function identifier and reason code.
* 3) The file and line number of the call that added the error.
* 4) A pointer to some error specific data, which may be NULL.
*
* The library identifier, function identifier and reason code are packed in a
* uint32_t and there exist various functions for unpacking it.
*
* The typical behaviour is that an error will occur deep in a call queue and
* that code will push an error onto the error queue. As the error queue
* unwinds, other functions will push their own errors. Thus, the "least
* recent" error is the most specific and the other errors will provide a
* backtrace of sorts. */
