rb_advance_reader

Name:rb_advance_reader

Proto:static void rb_advance_reader(struct ring_buffer_per_cpu *cpu_buffer)

Type:void

Parameter:

Type	Parameter	Name
struct ring_buffer_per_cpu *	cpu_buffer

3812

reader = rb_get_reader_page(cpu_buffer)

3815

If uffer may be either ring_buffer or ring_buffer_per_cpu (cpu_buffer, !reader) Then Return

3818

event = rb_reader_event(cpu_buffer)

3820

If type_len <= RINGBUF_TYPE_DATA_TYPE_LEN_MAX Then read++

3823

rb_update_read_stamp(cpu_buffer, event)

3825

length = Return the length of the given event. Will return* the length of the time extend if the event is a* time extend.

3826

dex for next read += length
