Returns task's free memory pages to the system memory pool.
Synopsis
int32 ScavengeMem( void )
Description
This procedure finds pages of memory in the task's free memory pool from which no memory is allocated and returns those pages to the system-wide memory pool.
If there is not enough memory in a task's free memory pool to satisfy a memory-allocation request, AllocMem() tries to get reclaim the necessary memory by calling ScavengeMem().
Return Value
The procedure returns the amount of memory that was returned to the system-wide memory pool, in bytes. If no memory was returned, the procedure returns 0.
