Hi,

im_memory.h : im_slice_delete

I'm not exactly sure what is achieved by the if(1) condition in the macro.

The following else statement can make sure that the pointer mem has correct type.

Doesn't it generate a 'condition always true' type of warning?

No it's there to generate a warning if the pointer passed is of a
different type.

im_slice_free accepts (essentially) a void. The else is there to
verify that Mem is of type struct_type.

The else clause will be optimised out.
