/* inout_typemaps.i |

Support for INPUT, OUTPUT, and INOUT typemaps. OUTPUT variables are returned |

as multiple values. |

/* Note that this macro automatically adds a pointer to the type passed in. |
|
As a result, INOUT typemaps for char are for 'char *'. The definition |
|
of typemaps for 'char' takes advantage of this, believing that it's more |
|
likely to see an INOUT argument for strings, than a single char. */ |
