The TCM_GETITEM message retrieves information about a tab in a tab control. You can send this message explicitly or by using the TabCtrl_GetItem macro.
TCM_GETITEM wParam = (WPARAM) (int) iItem; lParam = (LPARAM) (TC_ITEM FAR *) pitem;
If the mask member specifies the TCIF_TEXT value, the pszText member must contain the address of the buffer that receives the item text and the cchTextMax member must specify the size of the buffer.
Returns TRUE if successful or FALSE otherwise.
