Confused by CHAR

[Ducky]

I saw in a code the datatype CHAR (with uppercase).

I checked on MSDN and it says
"A string function that converts an int ASCII code to a character."

http://msdn.microsoft.com/en-us/library/aa258239(SQL.80).aspx 

CHAR* m_cCompleteBuffer = new CHAR [2096];

So how can it be a data type and a function at the same time?
Or is it the same as char (with lowercase)?
