## NAME

relay\_subbufs\_consumed - update the buffer's sub-buffers-consumed count

## SYNOPSIS

**void relay\_subbufs\_consumed(struct rchan \*** *chan***, unsigned int** *cpu***, size\_t** *subbufs\_consumed***);**

## ARGUMENTS

*chan*

the channel

*cpu*

the cpu associated with the channel buffer to update

*subbufs\_consumed*

number of sub-buffers to add to current buf's count

## DESCRIPTION

Adds to the channel buffer's consumed sub-buffer count. subbufs\_consumed should be the number of sub-buffers newly consumed, not the total consumed.
