## NAME

         freeList.c - General Purpose memory free list library

## SYNOPSIS

         freeListInitPvt     - Initialize a free list
         freeListCalloc - Allocate and initialize to zero a new element
         freeListMalloc - Allocate a new element
         freeListFree   - Free an element,i.e. put on free list

         void freeListInitPvt(void **ppvt,int size,int nmalloc);
         void *freeListCalloc(void *pvt);
         void *freeListMalloc(void *pvt);
         size_t freeListItemsAvail(void *pvt);
         void freeListFree(void *pvt,void*pmem);

         where :

         pvt  - For private use by library. Caller must provide a "void *pvt"
         size - Size in butes of each element. Note that all elements must be same size
         nmalloc   - Number of elements top allocate when regular malloc must be called.

## DESCRIPTION

         This library can be used to allocate  and  free  fixed  size
         memory  elements.   Free  elements  are maintained on a free
         list rather then being returned to the  heap  via  calls  to
         free.  When  it  is  necessary to call malloc, memory can be
         allocated in multiples of the element size.

## RETURNS

         freeListCalloc and freeListMalloc return address of element allocated
         or NULL if no more memory could be obtained via call to malloc
