NAME
       ERR_get_error, ERR_peek_error, ERR_peek_last_error,
       ERR_get_error_line, ERR_peek_error_line,
       ERR_peek_last_error_line, ERR_get_error_line_data,
       ERR_peek_error_line_data, ERR_peek_last_error_line_data -
       obtain error code and data

SYNOPSIS
        #include 

        unsigned long ERR_get_error(void);
        unsigned long ERR_peek_error(void);
        unsigned long ERR_peek_last_error(void);

        unsigned long ERR_get_error_line(const char **file, int *line);
        unsigned long ERR_peek_error_line(const char **file, int *line);
        unsigned long ERR_peek_last_error_line(const char **file, int *line);

        unsigned long ERR_get_error_line_data(const char **file, int *line,
                const char **data, int *flags);
        unsigned long ERR_peek_error_line_data(const char **file, int *line,
                const char **data, int *flags);
        unsigned long ERR_peek_last_error_line_data(const char **file, int *line,
                const char **data, int *flags);

DESCRIPTION
       ERR_get_error() returns the earliest error code from the
       thread's error queue and removes the entry. This function
       can be called repeatedly until there are no more error
       codes to return.

       ERR_peek_error() returns the earliest error code from the
       thread's error queue without modifying it.

       ERR_peek_last_error() returns the latest error code from
       the thread's error queue without modifying it.

       See ERR_GET_LIB(3) for obtaining information about loca-
       tion and reason of the error, and ERR_error_string(3) for
       human-readable error messages.

       ERR_get_error_line(), ERR_peek_error_line() and
       ERR_peek_last_error_line() are the same as the above, but
       they additionally store the file name and line number
       where the error occurred in *file and *line, unless these
       are NULL.

       ERR_get_error_line_data(), ERR_peek_error_line_data() and
       ERR_get_last_error_line_data() store additional data and
       flags associated with the error code in *data and *flags,
       unless these are NULL. *data contains a string if
       *flags&ERR_TXT_STRING. If it has been allocated by
       OPENSSL_malloc(), *flags&ERR_TXT_MALLOCED is true.

RETURN VALUES
       The error code, or 0 if there is no error in the queue.

HISTORY
       ERR_get_error(), ERR_peek_error(), ERR_get_error_line()
       and ERR_peek_error_line() are available in all versions of
       SSLeay and OpenSSL. ERR_get_error_line_data() and
       ERR_peek_error_line_data() were added in SSLeay 0.9.0.
       ERR_peek_last_error(), ERR_peek_last_error_line() and
       ERR_peek_last_error_line_data() were added in OpenSSL
       0.9.7.
