DESCRIPTION

       These functions are deprecated and are actually wrappers around other functions. You should use the other functions directly.

       Ns_ThreadAlloc(size)

	      A wrapper for Ns_ThreadMalloc.

       Ns_ThreadCalloc(nelem, elsize)

	      A wrapper for ns_calloc.

       Ns_ThreadFree(ptr)

	      A wrapper for ns_free.

       Ns_ThreadMalloc(size)

	      A wrapper for ns_malloc.

       Ns_ThreadPool()

	      Deprecated. Always returns a -1.

       Ns_ThreadRealloc(ptr, size)

	      A wrapper for ns_realloc.

       Ns_ThreadStrCopy(str)

	      A wrapper for ns_strcopy.

       Ns_ThreadStrDup(str)

	      A wrapper for ns_strdup.

DESCRIPTION

       The  AOLserver  memory  storage allocation code was moved into Tcl core beginning with Tcl 8.4.0. Starting with AOLserver 3.5, these memory
       allocation functions are wrappers that call Tcl_Alloc and Tcl_Free. Earlier versions of AOLserver used this fast memory	storage  allocator
       internally, or the platform's memory allocator depending on how you configured it.

       The  actual  amount  of	memory allocated or freed will be different from the requested amount.	This is because the fast memory allocation
       code pools memory into chunks and manages that memory internally.  In addition, the Tcl distribution may be compiled to allocate even  more
       memory  which  is used internally for diagnostic reasons. Using ns_free to free memory created by routines other than ns_malloc, ns_realloc
       and ns_calloc will almost certainly result in segmentation faults or undefined behavior.

       The lowercase and mixed-case versions are identical; the lowercase versions are preferred.

       ns_calloc(num, esize)
	      Allocates a block of memory that is num * esize large, zeros it, and returns a pointer to the beginning of the memory block or  NULL
	      if the operation fails.

       ns_free(ptr)
	      ns_free() frees the memory space pointed to by ptr. This pointer must have been created with a previous call to ns_malloc(), ns_cal-
	      loc() or ns_realloc().  If ptr is NULL, no operation is performed. ns_free() returns no value.

       ns_malloc(size)
	      ns_malloc() allocates size bytes and returns a pointer to the allocated memory.  The memory is not cleared. The value returned is  a
	      pointer to the allocated memory or NULL if the request fails.  The memory must be freed by ns_free.

       ns_realloc(ptr, size)
	      ns_realloc  changes  the size of the memory block pointed to by ptr to size bytes.  The contents will be unchanged to the minimum of
	      the old and new sizes. Newly allocated memory will be uninitialized.  If ptr is NULL, the call is equivalent to ns_malloc(size);	if
	      size is equal to zero, the call is equivalent to ns_free(ptr).  Unless ptr is NULL, it must have been returned by an earlier call to
	      ns_malloc(), ns_calloc() or ns_realloc().
