=pod =head1 NAME ERR_print_errors, ERR_print_errors_fp, ERR_print_errors_cb - print error messages =head1 SYNOPSIS #include 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, thus emptying the error queue. ERR_print_errors_fp() is the same, except that the output goes to a B. ERR_print_errors_cb() is the same, except that the callback function, B, is called for each error line with the string, length, and userdata B 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 is an 8 digit hexadecimal number. I, I and I are ASCII text, as is I 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. =head1 SEE ALSO L, L =head1 COPYRIGHT Copyright 2000-2017 The OpenSSL Project Authors.
