Question about kernel32.dll and MT5...

[cyberglassed]

Hello, reading this article:
https://www.mql5.com/en/articles/115
on how to use named pipes, I noticed that on the file attached at the end of the article: cnamedpipes.mqh
direct link: http://p.mql5.com/data/2/115/cnamedpipes.mqh
there is an import of the library: kernel32.dll
and bellow of that there is one definition of the function: "WriteFile" as follows:
int WriteFile(int fileHandle, MqlTick & outgoing, int bytes, int &numOfBytes, int overlapped);

but, on the following page:
http://msdn.microsoft.com/en-us/library/aa365747%28v=vs.85%29.aspx

the "WriteFile" function doesn't have this signature, also, I think the type: "MqlTick" is MT5 specific,

so, I would like to know where the type MqlTick cames from, and by the way, that WriteFile function?

Thanks in advance, Cyberglassed.

thank you luenbo, but i would like to know where is defined the function:

int WriteFile(int fileHandle, MqlTick & outgoing, int bytes, int &numOfBytes, int overlapped);

with the MqlTick parameter inside?

kernel32.dll?, or somewhere?

thanks, Cyberglassed.
