NAME
- QueryKeys
-
return the states for a set of keys. (V40)
SYNOPSIS
QueryKeys(queryArray, arraySize);
VOID QueryKeys(struct KeyQuery *, UBYTE);
A0 D1
FUNCTION
Scans the keyboard to determine which of the rawkey codes listed in the QueryArray are currently pressed. The state for each key is returned in the array.
This function may be invoked from within an interrupt, but the size of QueryArray should be kept as small as possible.
This is a low level function that does not fit the normal Amiga multitasking model. The values returned have no knowledge of which window/screen currently has input focus.
