VeryLongFunction()
------------------

Very long function brief description.

CALLING SEQUENCE:
    .. code-block:: c

        int VeryLongFunction(
          int                  VeryLongParam0,

        );

DIRECTIVE PARAMETERS:
    VeryLongParam0
        This parameter is very long parameter 0 with some super important and
        extra very long description which makes a lot of sense.

    VeryLongParam1
        This parameter is very long parameter 1.

    VeryLongParam2
        This parameter is very long parameter 2.

    VeryLongParam3
        This parameter is very long parameter 3.

DIRECTIVE RETURN VALUES:
    1
