 #line                   Line Control

 #line integer-constant ["filename"]
 or
 #line macro_name

    Instructs the preprocessor to change the current line number to
    integer-constant and the current source file name to filename.

      Notes:    This directive is typically used by programs that
                automatically generate C source.

                integer-constant is interpreted as a decimal number.

                If filename is omitted, the current file name is
                unchanged.

                The current line number and file name are always
                available through the predefined macros __LINE__ and
                __FILE__, respectively.
