| int GetClassName(hwnd, lpClassName, cchClassName) | |||||

This function retrieves the class name of the window specified by the hwnd parameter.
hwnd
Identifies the window whose class name is to be retrieved.
lpClassName
Points to the buffer that is to receive the class name.
cchClassName
Specifies the maximum number of characters to be stored in the lpClassName parameter. If the actual name is longer, a truncated name is copied to the buffer.
The return value specifies the number of characters actually copied to lpClassName. The return value is zero if the specified class name is not valid.
The GetClassName function may be used as either a wide-character function (where text arguments must use Unicode) or an ANSI function (where text arguments must use characters from the Windows 3.x character set installed).
