rbfparms(2) - Linux man page

Name

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

#include <bfreq.h>

int rbfparms (int node, int *parms);
int rbfsweep (int node);
int rbfsweep1 (int node, int event);
int rbfwipe (int node);

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). 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.
