R0 = 12
R2 = size of block required
Exit:
R1 = pointer to anchor or zero if allocation failed
Tries to find a block of the required size. Increases the WimpSlot if necessary. If a call to Wimp_SlotSize fails then zero will be returned. Note that the size is rounded up to the next multiple of 8 plus 4. If no free anchors are available then the increase anchors call is used to make some more; therefore using this SWI can cause blocks to be relocated. It is, however, the recommended call to use for allocating blocks as it isn't limited by the number of anchors already created.
