# io\_uring\_buf\_ring\_advance(3)

advance index of provided buffer in buffer ring

## NAME

io\_uring\_buf\_ring\_advance - advance index of provided buffer in buffer ring

## SYNOPSIS

```
#include <liburing.h>
```

**void io\_uring\_buf\_ring\_advance(struct io\_uring\_buf\_ring \****br***,**                                **int** *count***);**

## DESCRIPTION

The [**io\_uring\_buf\_ring\_advance**(3)](/io_uring_buf_ring_advance/3.md) commits *count* previously added buffers to the shared buffer ring *br*, making them visible to the kernel and hence consumable. This passes ownership of the buffer to the ring.

## RETURN VALUE

None
