Remarks

There is no import library available that defines this function, so it is necessary to obtain a pointer to this function using LoadLibrary and GetProcAddress.

The definition of LAYOUTORTIP is:

typedef struct tagLAYOUTORTIP {
    DWORD dwFlags;
#define LOT_DEFAULT    0x0001 // If this is on, this is a default item. 
#define LOT_DISABLED   0x0002 // if this is on, this is not enabled. 
    WCHAR szId[MAX_PATH]; // Id of the keyboard item in the string format. 
    WCHAR szName[MAX_PATH]; // The description of the keyboard item. 
} LAYOUTORTIP;
