479 * Name : DWORD GetCharacterPlacementW

485 * The function copies the information to the specified GCP_RESULTSW

487 * Parameters: HDC hdc handle to device context
488 * LPCSTR lpString pointer to string
489 * int nCount number of characters in string
490 * int nMaxExtent maximum extent for displayed string
491 * GCP_RESULTSW *lpResults pointer to buffer for placement result
