:A question about the slab allocator. Did you write INTO the the slab
:allocator the undocumented items from malloc? Or did you use a type of
:wrapper or extra function call for these "gotchas" so that the slab
:allocator is consistent and those programs that need the other items get
:access/use of the slab allocator through the wrapper or whatever?
:I'm curious as to not only what choice was made, BUT more importantly
:why that choice was made.
:Thank You & Still learning
The undocumented items have been built (integrated) into the slab
allocator, primarily because the biggest undocumented item is the
power-of-2 alignment for power-of-2 sized blocks, and that is not
something a wrapper could easily or efficiently implement. Also, we
are only talking about a few lines of code. Eyesores, yes, but still
only a few lines of code.
