GetHandleInformation

The GetHandleInformation function obtains information about certain properties of an object handle. The information is obtained as a set of bit flags.

BOOL GetHandleInformation (

HANDLE hObject,	// handle to an object
LPDWORD lpdwFlags	// points to variable to receive flags
);

Parameters

hObject

Specifies a handle to an object. The GetHandleInformation function obtains information about this object handle.

lpdwFlags

Points to a variable to receive a set of bit flags that specify properties of the object handle. The following flags are defined:

Value	Meaning
HANDLE_FLAG_INHERIT	If this flag is set, a child process created with the bInheritHandles parameter of CreateProcess set to TRUE will inherit the object handle.
HANDLE_FLAG_PROTECT_FROM_CLOSE	If this flag is set, calling the CloseHandle function will not close the object handle.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.
