     ERR_get_error() returns the earliest error code from the
     thread's error queue and removes the entry. This function
     can be called repeatedly until there are no more error codes
     to return.

     ERR_peek_error() returns the earliest error code from the
     thread's error queue without modifying it.

     ERR_peek_last_error() returns the latest error code from the
     thread's error queue without modifying it.

     See ERR_GET_LIB(3) for obtaining information about location
     and reason of the error, and ERR_error_string(3) for human-
     readable error messages.

     ERR_get_error_line(), ERR_peek_error_line() and
     ERR_peek_last_error_line() are the same as the above, but
     they additionally store the file name and line number where
     the error occurred in *ffffiiiilllleeee and *lllliiiinnnneeee, unless these are
     NNNNUUUULLLLLLLL.

     ERR_get_error_line_data(), ERR_peek_error_line_data() and
     ERR_get_last_error_line_data() store additional data and
     flags associated with the error code in *ddddaaaattttaaaa and *ffffllllaaaaggggssss,
     unless these are NNNNUUUULLLLLLLL. *ddddaaaattttaaaa contains a string if

     ERR_get_error(), ERR_peek_error(), ERR_get_error_line() and
     ERR_peek_error_line() are available in all versions of
     SSLeay and OpenSSL. ERR_get_error_line_data() and
     ERR_peek_error_line_data() were added in SSLeay 0.9.0.
     ERR_peek_last_error(), ERR_peek_last_error_line() and
     ERR_peek_last_error_line_data() were added in OpenSSL 0.9.7.
