Pointer to an LV_ITEM structure that
specifies the information to retrieve and receives information about the list
view item.
When the LVM_GETITEM message is sent, the iItem and iSubItem
members identify the item or subitem to retrieve information about and the mask
member specifies which attributes to retrieve. For a list of possible values,
see the description of the LV_ITEM
structure.
If the mask member specifies the LVIF_TEXT value, the pszText
member must contain the pointer to the buffer that receives the item text and
the cchTextMax member must specify the size of the buffer.
If the mask member specifies the LVIF_STATE value, the stateMask
member must specify the item state bits to retrieve. On output, the state
member contains the values of the specified state bits.
