 * typemaps.i.
 *
 * SWIG Typemap library for PHP.
 *
 * This library provides standard typemaps for modifying SWIG's behavior.
 * With enough entries in this file, I hope that very few people actually
 * ever need to write a typemap.
 *
 * Define macros to define the following typemaps:
 *
 * TYPE *INPUT.   Argument is passed in as native variable by value.
 * TYPE *OUTPUT.  Argument is returned as an array from the function call.
 * TYPE *INOUT.   Argument is passed in by value, and out as part of returned list
 * TYPE *REFERENCE.  Argument is passed in as native variable with value
 *                   semantics.  Variable value is changed with result.
 *                   Use like this:
 *                   int foo(int *REFERENCE);
 *
 *                   $a = 0;
 *                   $rc = foo($a);
 *
 *                   Even though $a looks like it's passed by value,
 *                   its value can be changed by foo().
