# rbfparms(2)

Control LAM remote buffers.

## NAME

rbfparms, rbfsweep, rbfsweep1, rbfudie, rbfwipe - Control LAM remote buffers.

## SYNOPSIS

```
#include <bfreq.h>
int rbfparms (int node, int *parms);
int rbfsweep (int node);
int rbfsweep1 (int node, int event);
int rbfwipe (int node);
```

## DESCRIPTION

The remote function *rbfparms()* sets overall buffer parameters on the given *node*.

Updated values are supplied in a buffer parameter structure, *bfparms*, defined in \<bfreq.h\>.

```
struct bfparms {
	int	bfp_maxspace;
	int	bfp_nspace;
};
```

Not all fields in the structure control buffer parameters. The same structure is used to return overall buffer status with [rbfstate(2)](/rbfstate/2.md). The controllable fields are listed below. If set to -1, the current value in the remote buffer daemon is maintained, otherwise the value is updated.

- bfp\_maxspace

  maximum space that a buffer daemon will allocate for message buffers

### Cleaning Buffers

A prematurely terminated application will frequently leave messages in buffers.

*rbfsweep()* clears all buffered messages on a given *node*.

*rbfsweep1()* clears all messages with a given *event* on a given *node*.

*rbfwipe()* completely resets the state of the buffer daemon on a given *node*. All buffered messages and any other information are lost.
