/* pydtrace_probes.h, on systems with DTrace, is auto-generated to include

`PyDTrace_{PROBE}` and `PyDTrace_{PROBE}_ENABLED()` macros for every probe

defined in pydtrace.d.

Calling these functions must be guarded by a `PyDTrace_{PROBE}_ENABLED()`

check to minimize performance impact when probing is off. For example:

if (PyDTrace_FUNCTION_ENTRY_ENABLED())

PyDTrace_FUNCTION_ENTRY(f);

#else
