Use
The purpose of this call is to search all icons within a specific window for an icon with an icon flag that matches the pattern specified in R3.
Notes
For each icon that matches the search criteria, its handle number is added to the block pointed to by R1.
The list of returned icon handles are terminated by a value of -1.
The mask value in R2 is used to specify which bits are used to compare against. An example of how this call works is shown below.
(icon flags AND R2) = (R3 AND R2)
