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

     SYNOPSIS
           #include <openssl/err.h>

           unsigned long ERR_get_error(void);
           unsigned long ERR_peek_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_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);

     DESCRIPTION
          ERR_get_error() returns the last 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 last error code from the
          thread's error queue without modifying it.

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

          ERR_get_error_line() and ERR_peek_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() and ERR_peek_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.

          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.
