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). 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.
