C

Displays the current status of the console buffer pool. End of change

cpid

Displays the current status of the specified cell pool. Currently, the following cell pools are supported:

The following items are displayed for each type of buffer pool except as noted:

The number of buffers or cells in use.
The maximum number of buffers or cells used.
The number of secondary extents in use.
The maximum number of secondary extents used.
The number of reserved buffers in use (consoles only).
The maximum number of reserved buffers used (consoles only).

R

Resets the console buffer counters to the number currently in use. The following counter is reset:

The maximum number of console buffers used.
The maximum number of secondary extents used.
The maximum number of reserved buffers used.
