_heapmin Functions
◄Summary► ◄Example► ◄Up► ◄Contents► ◄Index► ◄Back►
─────Run-Time Library───────────────────────────────────────────────────────
The functions in the _heapmin family minimize the heap by
releasing unused memory in the heap to the operating system.
The various _heapmin functions release unused memory in these
heaps:
Function Heap Minimized
_heapmin Depends on data model of program
_bheapmin Based heap specified by seg value; _NULLSEG
specifies all based heaps
_fheapmin Far heap (outside default data segment)
_nheapmin Near heap (inside default data segment)
With large data models (that is, compact-, large-, and huge-model
programs), _heapmin maps to _fheapmin. In small data models
(tiny-, small-, medium-model programs), _heapmin maps to
_nheapmin.
For _heapmin, if the supplied <seg> value is _NULLSEG, all based
heap segments are minimized; otherwise, only the specified one is
minimized.
Based-heap segments are never freed (that is, unlinked from the
based-heap list and released back to the operating system) by the
_bheapmin function. The _bfreeseg function is used for that
purpose.
Return Value
The _heapmin functions return 0 if the function completed
successfully, or -1 in the case of error.
