+ * 	Write raw *data* blob into a special BPF perf event held by
+ * 	*map* of type **BPF_MAP_TYPE_PERF_EVENT_ARRAY**. This perf
+ * 	event must have the following attributes: **PERF_SAMPLE_RAW**
+ * 	as **sample_type**, **PERF_TYPE_SOFTWARE** as **type**, and
+ * 	**PERF_COUNT_SW_BPF_OUTPUT** as **config**.
+ *
+ * 	The *flags* are used to indicate the index in *map* for which
+ * 	the value must be put, masked with **BPF_F_INDEX_MASK**.
+ * 	Alternatively, *flags* can be set to **BPF_F_CURRENT_CPU**
+ * 	to indicate that the index of the current CPU core should be
+ * 	used.
+ *
+ * 	The value to write, of *size*, is passed through eBPF stack and
+ * 	pointed by *data*.
+ *
+ * 	*ctx* is a pointer to in-kernel struct xdp_buff.
+ *
+ * 	This helper is similar to **bpf_perf_eventoutput**\ () but
+ * 	restricted to raw_tracepoint bpf programs.
+ *
+ * Returns
+ * 	0 on success, or a negative error in case of failure.
