Field Documentation

size_t EGmemPool_t::allocMem

total amount of memory alloc'ed from the pool Definition at line 255 of file eg_mempool.h.

unsigned int EGmemPool_t::cBigBlocks[__EG_MEMPOOL_N_BIG_CHUNKS__]

Definition at line 247 of file eg_mempool.h.

size_t* EGmemPool_t::curUsedMem

memory currently in use per size Definition at line 267 of file eg_mempool.h.

void* EGmemPool_t::freeArrayHead

the memory is stored in two ways, we have an array of memory from were we return to the system, but if we run out of these memory we look to the 'freed' memory and if that is empty we alloc another array of memory. This pointer points to the begining of the 'freeArray' Definition at line 216 of file eg_mempool.h.

size_t EGmemPool_t::freeArraySize

how many bytes are free in the freeArray Definition at line 219 of file eg_mempool.h.

void** EGmemPool_t::freedMemory

this array store list of 'freed' memory, the lists are indexed acording to the size of the memory freed (discretized by the size of (void*) ) Definition at line 224 of file eg_mempool.h.

size_t EGmemPool_t::manageLimit

this define up to what size of memory we manage through the pool, if we ask the pool for memory over this size the pool will only call malloc/free Definition at line 229 of file eg_mempool.h.

size_t EGmemPool_t::maxBlock

maximum non managed block of memory asked to the pool Definition at line 242 of file eg_mempool.h.

const char* EGmemPool_t::maxBlockFile

Definition at line 243 of file eg_mempool.h.

int EGmemPool_t::maxBlockLine

Definition at line 244 of file eg_mempool.h.

size_t* EGmemPool_t::maxUsedMem

maximum memory alloc'ed at the same time per size Definition at line 264 of file eg_mempool.h.

const char* EGmemPool_t::memAllocationFile

where (which file) the pool was created Definition at line 238 of file eg_mempool.h.

int EGmemPool_t::memAllocationLine

where (which line) the pool was created Definition at line 239 of file eg_mempool.h.

void** EGmemPool_t::MemoryList

and array of size MemoryListSize that contains a pointer to each memory chunk that we have alloc'ed Definition at line 206 of file eg_mempool.h.

size_t EGmemPool_t::MemoryListSize

store the size of MemoryList Definition at line 209 of file eg_mempool.h.

unsigned int EGmemPool_t::nBigBlocks[__EG_MEMPOOL_N_BIG_CHUNKS__]

Definition at line 245 of file eg_mempool.h.

size_t(* EGmemPool_t::newsize)(size_t)

a function that return the size (in bytes) of the i-th memory block

size_t EGmemPool_t::nNullAlloc

null alloc information Definition at line 250 of file eg_mempool.h.

size_t EGmemPool_t::noManageMem

memory alloc'ed by the pool but not managed Definition at line 261 of file eg_mempool.h.

const char* EGmemPool_t::nullAllocFile

Definition at line 251 of file eg_mempool.h.

int EGmemPool_t::nullAllocLine

Definition at line 252 of file eg_mempool.h.

unsigned int EGmemPool_t::sBigBlocks[__EG_MEMPOOL_N_BIG_CHUNKS__]

Definition at line 246 of file eg_mempool.h.

size_t EGmemPool_t::totalMem

memory really alloc'ed by the pool Definition at line 258 of file eg_mempool.h.
