NAME

       ERR_print_errors, ERR_print_errors_fp, ERR_print_errors_cb - print error messages

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)

DESCRIPTION

       ERR_print_errors() is a convenience function that prints the error strings for all errors
       that OpenSSL has recorded to bp, thus emptying the error queue.

       ERR_print_errors_fp() is the same, except that the output goes to a FILE.

       ERR_print_errors_cb() is the same, except that the callback function, cb, is called for
       each error line with the string, length, and userdata 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]

       error code is an 8 digit hexadecimal number. library name, function name and reason string
       are ASCII text, as is 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.

RETURN VALUES

       ERR_print_errors() and ERR_print_errors_fp() return no values.
