* Every builtin function "foo" called by a systemtap script is
* translated to a C call to a C function named "function_foo". This
* is the function you must provide in this file. In addition, the
* translator emits a

* #define _BUILTIN_FUNCTION_foo_

* function definitions which are not used by a given systemtap
