I tried hard to keep the lines at 80 characters or less, but in a few cases I had to punt and just indented the subsequent lines by 4 spaces. A few well-placed typedefs for callback functions would really help, but these would be part of the API, so that's probably for later. I also took the liberty of inserting empty lines in overlong blocks to provide some visual space.

=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.
