Ring buffer vs HeapAlloc

[jj2007]

interesting .. sort of JJ .. but i presume youve hard coded the buffer into the data area ??

Yes.

include \masm32\MasmBasic\MasmBasic.inc
  Init
  Recall "\Masm32\include\Windows.inc", L$()
  Dim out$(eax)
  NanoTimer()
  For_ ecx=0 To L$(?)-1
        ; uses the ringbuffer 3x26906 = 80706 times:
        Let out$(ecx)=Str$("String #%i\t", ecx)+Left$(L$(ecx), 20)+" ... "+Right$(L$(ecx), 8)
  Next
  Inkey NanoTimer$(), Str$(" for creating %i strings", ecx)
  Store "outstrings.txt", out$()
  ShEx  "outstrings.txt"
EndOfCode

Code Select Expand

15 ms for creating 26902 strings

Show me how to do it faster with HeapAlloc.

As the MAC user would say, mammory is mammory, wotz the big deal.

If you have a start address and know the length boundary of the memory, the MAC user with a slight spelling change is correct.
