Description

This page describes the MemMEvent interface.

A module only needs to implement the functions it needs.

0x00 - LowMem

Syntax

void LowMem(int severity);

Properties

• System
• Phase 1

Description

This function is called to signal that system memory is low and modules should free memory.

Receiving this event a module that implements a buffer can free unused buffers, etc.

severity says how much memory is needed:

• 0x01 - system with low memory (free a little of memory, for instance: disk buffers that aren`t used for a long time; 10% of all buffers, etc)
• 0x02 - system close to the minimum of necessary free memory (free a lot of memory, for instance: all disk buffers that aren`t dirty, 70% of all buffers, etc)
• 0x03 - system in critical limit (free all memory available in buffers)

Return value

Nothing.
