WS_HEAP_PROPERTY_ID enumeration (webservices.h)

Each heap property is identified by an ID and has an associated value.

Syntax

typedef enum {
  WS_HEAP_PROPERTY_MAX_SIZE = 0,
  WS_HEAP_PROPERTY_TRIM_SIZE = 1,
  WS_HEAP_PROPERTY_REQUESTED_SIZE = 2,
  WS_HEAP_PROPERTY_ACTUAL_SIZE = 3
} WS_HEAP_PROPERTY_ID;

Constants

WS_HEAP_PROPERTY_MAX_SIZE Value: 0 Used with WsGetHeapProperty. Returns the total number of bytes that can be allocated from the heap. The total number of bytes is defined as sum of the sizes passed in all the calls to WsAlloc since the heap was created / reset.
WS_HEAP_PROPERTY_TRIM_SIZE Value: 1 Used with WsGetHeapProperty. Returns the maximum number of bytes of memory that the heap will retain after a call to WsResetHeap call. This should be treated an approximate value due to heap overhead. If the trim size is larger than the max size, then the size of the heap will not be trimmed.
WS_HEAP_PROPERTY_REQUESTED_SIZE Value: 2 Used with WsGetHeapProperty. Returns the current total number of bytes requested from the heap since the heap was created/reset.
WS_HEAP_PROPERTY_ACTUAL_SIZE Value: 3 Used with WsGetHeapProperty. Returns the current total number of bytes that the WS_HEAP has allocated from the operating system for purposes of providing allocations.
