ERR_print_errors(3)                 OpenSSL                ERR_print_errors(3)



NAME
       ERR_print_errors, ERR_print_errors_fp, ERR_print_errors_cb - print
       error messages

LIBRARY
       libcrypto, -lcrypto

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]:[filename]:[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.
