Hello,
I am Profiling my code using the MS Visual Studio 2005 Profiler-Instrumentation Profiling, to make it as efficient as possible. I have a few doubts regarding the Profiled data results and want help in its analysis.
In the Summary Tab of the Profiled output, it shows

Functions with most individual work and Functions taking longest:
Name Time(msec) %
THUNK:<CrtImplementationDetails>::DoDllLanguageSupportValidation 11034.162019 70.697
.corfunc(float64,float64,float32,int8*,int32*) 981.766243 6.290

In this, corfunc() is a User Defined Function which I have written. Now what I don't understand is the one above it i.e
What is DoDllLanguageSupportValidation? Do I have control over it? Can I do something to reduce its time consumption.
The same is also seen in the Functions Tab as shown below:
Function Name No of calls Elapsed Exclusive
THUNK:<CrtImplementationDetails>::DoDllLanguageSupportValidation 1 11034.162019

Also In the Call Tree Tab I observed another within the main() function which I donot understand completely. Is the below function referring to the double datatype? or (double) typecast:
std::basic_ostream<char,struct std::char_traits<char> >::operator<<(double) 101 486.371922

Thanks,

I'm not sure about this, but I believe DoDllLanguageSupportValidation() is actually loading a .dll, so you can use the functions in it. Depending on the .dll, this could involve loading in several hundred functions.

If it is loading a .dll, you can manually load a .dll with
LoadLibrary() - To "open" the dll
GetProcAddress() - To get the functions from the dll
FreeLibrary() - To "close" the dll

but it is far more complicated, and a lot messier.

Hello,
I am including some header files in my code. Is that what the .dll referring to? I donot understand much. Please reply to each doubt of mine in the first post individually.
Thank you for your patience,
prads
