=head1 NAME
ERR_print_errors, ERR_print_errors_fp, ERR_print_errors_cb
- print error messages
=head1 SYNOPSIS
#include <openssl/err.h>
void ERR_print_errors(BIO *bp);
void ERR_print_errors_fp(FILE *fp);
void ERR_print_errors_cb(int (*cb)(const char *str, size_t len, void *u),
void *u)
=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>.
ERR_print_errors_cb() is the same, except that the callback function,
B<cb>, is called for each error line with the string, length, and userdata
B<u> as the callback parameters.
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.
