Re: what syntax is this? hex3-Jan-02 19:46 hex 3-Jan-02 19:46  i dont understand the " throw() ",does it break the definition of the function GetInterfacePtr()? thanks Re: what syntax is this? Michael Dunn3-Jan-02 19:58 Michael Dunn 3-Jan-02 19:58  Ah, ok, that indicates to the compiler that the function never throws any exceptions. --Mike-- My really out-of-date homepage Buffy's on.

Re: what syntax is this? hex3-Jan-02 20:11 hex 3-Jan-02 20:11  then if it is "throw (type)" ,what is the meaning ? would you please tell me where i can find the explanation of the syntax ? thanks Re: what syntax is this? markkuk3-Jan-02 23:36 markkuk 3-Jan-02 23:36  It would mean that the function may throw only exceptions of class "type". Look up "exception specification" in some proper C++ reference. Exception specifications aren't supported by VC++6. Re: what syntax is this? Michael Dunn4-Jan-02 8:03 Michael Dunn 4-Jan-02 8:03  markkuk wrote: Exception specifications aren't supported by VC++6. You sure about that? The first hit in MSDN when searching for "exception specification" shows examples of VC code using exception specifications. --Mike-- My really out-of-date homepage Buffy's on. Gotta go, bye!

Carlos Antollini4-Jan-02 8:11 Carlos Antollini 4-Jan-02 8:11  Michael may be this gauy is confused for the following: Microsoft Specific —> Microsoft C++ does not support the function exception specification mechanism, as described in section 15.4 of the ANSI C++ draft. I found that in the MSDN under Exception Handling Syntax It's a little confuss butc don't said that VC doesn't support Exception specifications... Reagards... Today is Friday!!! and Party!!!

First up How do I determine where to start to map in memory? I am using NT so how do I know how much it is using. And if you can help , how would you go about mapping large files in the first place? Thanks Re: Memory Mapping Philip Patrick4-Jan-02 2:52 Philip Patrick 4-Jan-02 2:52  The functions will tell you exactly where the mapping starts. Use CreateFileMapping() to create a mapping to file and MapViewOfFile() to load a portion (or all file) into memory. The last function will return you LPBYTE, points to the start of mapping Look for descriptions of the functions in MSDN.

While I would expect and simple array to be faster I was surprised at the amount of difference. Using the two functions below I got the following timing results. FooList: 0.0013247494 seconds FooArray: 0.0000005587 seconds std::list<DWORD> FooList() { std::list<DWORD> list; for(int x = 0; x < 50; x++) list.push_back(x); return list; } void FooArray(DWORD* list) { for(int x = 0; x < 50; x++) list[x] = x; } Re: STL optimization Christian Graus3-Jan-02 15:10 Christian Graus 3-Jan-02 15:10  It depends - what STL implimentation are you using ? I admit I've never done this sort of testing, but while I'd expect some overhead, I assume you're using the version that comes with VC for results as poor as this. Christian I have come to clean zee pooollll. - Michael Martin Dec 30, 2001 Sonork ID 100.10002:MeanManOzI live in Bob's HungOut now Re: STL optimization Not Active4-Jan-02 1:18 Not Active 4-Jan-02 1:18  I am using the VC version, never gave it a thought. What other implementations have you worked with? Re: STL optimization Thomas Freudenberg4-Jan-02 1:45 Thomas Freudenberg 4-Jan-02 1:45  You are talking about arrays, but your sample uses std::list Maybe you should change your code to following: std::list<int> FooList() { std::list<int> list; for(int x = 0; x < 50; x++) list.push_back(x); return list; } Regards Thomas Finally with Sonork id: 100.10453 Thömmi Disclaimer: Because of heavy processing requirements, we are currently using some of your unused brain capacity for backup processing.
