Maybe this can help you: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/memory/base/memory_management.asp Microsoft says that HeapAlloc is faster than GlobalAlloc (and has more options)... I've not tested that (about the speed). |

From what I read it seems that heap functions should be used to allocate smaller blocks of memory, while GlobalAlloc - for bigger ones.
Perhaps f0dder could tell much more about this topic... |

I have just found accidentally f0dder's article about it. Maybe it helps.
Go to http://f0dder.has.it/ -> Articles -> Memory allocation ramblings |

thx...
it was about fasmlib. does it need to call GlobalAlloc, or can be all allocation done via HeapAlloc. Does anybody know how do the HLLs treat this? A i know, in DOS and Linux everything is heap. |

According to f0dder, Gobal/LocalAlloc both end up using HeapAlloc so you may as well just use it in the first place
 .
P.S. I think Gobal/LocalAlloc are left over from 16bit Windows, pre 9x. |
