Detailed Description

A class which provides memory pointers and allows users to claim a pointer. If a memory items is claimed, that memory item is not returned until all that claimed it, release it. Multiple users can claim the same item. If there's no unclaimed memory, it creates some.

Constructor & Destructor Documentation

◆ CMemRing()

CMemRing::CMemRing	(	__int64	ll_size,
		int	nMinElems,
		int	nMaxElems
	)

ll_size is the size that the memory blocks will be.

Member Function Documentation

◆ GetFree()

void * CMemRing::GetFree ( int * pnIdx )

Returns a pointer of memory that is uncalimed. Creates one if it cannot find any. pnIdx gets the index value of the memory.

Definition at line 57 of file mem pool.cpp.

◆ GetIndexMemory()

void * CMemRing::GetIndexMemory ( int nIdx )

Takes a index to memory item, returns the memory pointer, and adds a claim to the pointer.

Definition at line 26 of file mem pool.cpp.

◆ GetIndexMemoryUnsafe()

void * CMemRing::GetIndexMemoryUnsafe ( int nIdx )

Takes a index to memory item, returns the memory pointer, however it does not add a claim to the pointer.

Definition at line 39 of file mem pool.cpp.

◆ ReleaseIndex()

void CMemRing::ReleaseIndex ( int nIdx )

Releases a claim to a memory item.

Definition at line 49 of file mem pool.cpp.

Member Data Documentation

◆ m_llSize

const __int64 CMemRing::m_llSize

The size of the memory blocks.

Definition at line 78 of file mem pool.h.

◆ m_nMaxElems

const int CMemRing::m_nMaxElems

The maximum number of elements m_apMemory can ever have.

Definition at line 82 of file mem pool.h.

◆ m_nMinElems

const int CMemRing::m_nMinElems

The minimum number of elements m_apMemory can ever have.

Definition at line 80 of file mem pool.h.
