One of the many error codes returned by GetLastError, which should not be used within the .NET framework. Instead you must use Marshal.GetLastWin32Error().

It is documented that you should NOT use the pinvoke GetLastError() due to the fact that the runtime

If no error occurs, sendto returns the total number of bytes sent, which can be less than the number indicated by len. Otherwise, a value of SOCKET_ERROR is returned, and a specific error code can be retrieved by calling WSAGetLastError.

If the function cannot find an account name for the SID, the LookupAccountSid function fails and GetLastError returns ERROR_NONE_MAPPED. This can occur if a network time-out prevents the function from finding the name. It also occurs for SIDs that have no corresponding account name, such as a logon SID that identifies a logon session.

It is recommended that you do not call the Win32 GetLastError method directly. Because of the way P/Invoke works, the error message may get reset between Win32 calls in your code. Instead, call the Marshal.GetLastWin32Error method, which can be combined with the ever useful Marshal.ThrowExceptionForHR method. See below for an example.

Int32 lastError = GetLastError();

lastError = GetLastError()

3 - SYSMEM_FAILED: Change failed. Use GetLastError to get more details.

     int error = Marshal.GetLastWin32Error();    // Equivalent to Win32 GetLastError()

WAIT_FAILED indicates failure. To get extended error information, call GetLastError.

Do not use GetLastError with the return values of this function.

If the function succeeds, the return value is a handle to the newly created device-independent bitmap (and ppvBits will point to the bitmap’s bit values). If the function fails, the return value is NULL (and ptr ppvBits will be NULL). To get extended error information, call GetLastError.

When you call this function, the WndProc function must respond to the WM_NCCREATE message by returning TRUE. If it does not, the creation process will fail. A null handle will be returned from CreateWindowEx and GetLastError will return 0. See MSDN on WM_NCCREATE (http://msdn.microsoft.com/en-us/library/ms632635.aspx) and also WM_CREATE (http://msdn.microsoft.com/en-us/library/ms632619.aspx). You can have your WndProc call DefWindowProc, which will take care of this issue.

SP_COPY_NOOVERWRITE Copy only if the specified files don't currently exist in the INF directory. If the INF does currently exist, this API will fail and GetLastError returns ERROR_FILE_EXISTS. In this case, the existing INF file's filename will be placed into the appropriate field in the destination INF file's information output buffers.

in Size of the DestinationInfFileName buffer, in characters, or zero if the buffer is not specified. If DestinationInfFileName is specified and this buffer size is less than the size required to return the destination INF filename (including full path), this function will fail. In this case GetLastError will return ERROR_INSUFFICIENT_BUFFER.

in Zero-based index to the list of interfaces in the device information set. You should first call this function with the MemberIndex parameter set to zero to obtain the first interface. Then, repeatedly increment MemberIndex and retrieve an interface until this function fails and GetLastError returns ERROR_NO_MORE_ITEMS (259).

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