Revision a520723f29aac6598ff0d69e34f5e9b88213e511 authored by Matt Caswell on 14 October 2016, 12:07:00 UTC, committed by Matt Caswell on 28 October 2016, 08:43:41 UTC
The previous commit inspired a review of all the length checks for the extension adding code. This adds more robust checks and adds checks where some were missing previously. The real solution for this is to use WPACKET which is currently in master - but that cannot be applied to release branches. Reviewed-by: Rich Salz <rsalz@openssl.org>

=head1 NAME
ERR_print_errors, ERR_print_errors_fp - print error messages
=head1 SYNOPSIS
#include <openssl/err.h>
void ERR_print_errors(BIO *bp);
void ERR_print_errors_fp(FILE *fp);
=head1 DESCRIPTION
ERR_print_errors() is a convenience function that prints the error
strings for all errors that OpenSSL has recorded to B<bp>, thus
emptying the error queue.
ERR_print_errors_fp() is the same, except that the output goes to a
B<FILE>.
The error strings will have the following format:
[pid]:error:[error code]:[library name]:[function name]:[reason string]:[file name]:[line]:[optional text message]
I<error code> is an 8 digit hexadecimal number. I<library name>,
I<function name> and I<reason string> are ASCII text, as is I<optional
text message> if one was set for the respective error code.
If there is no text string registered for the given error code,
the error string will contain the numeric code.
=head1 RETURN VALUES
ERR_print_errors() and ERR_print_errors_fp() return no values.
