Name:g_buffer_bytes_cpu - get the number of bytes consumed in a cpu buffer*@buffer: The ring buffer*@cpu: The per CPU buffer to read from.
Proto:unsigned long ring_buffer_bytes_cpu(struct ring_buffer *buffer, int cpu)
Type:unsigned long
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct ring_buffer * | buffer | |
| int | cpu |
| 3386 | If Not pumask_test_cpu - test for a cpu in a cpumask*@cpu: cpu number (< nr_cpu_ids)*@cpumask: the cpumask pointer* Returns 1 if @cpu is set in @cpumask, else returns 0 Then Return 0 |
| 3389 | cpu_buffer = buffers[cpu] |
| 3390 | ret = local_read( & entries_bytes) - read_bytes |
| 3392 | Return ret |
