2 isblk - whether or not a value is a block
13 isblk(val) returns 1 if val is an unnamed block, 2 if val is a
14 named block, 0 otherwise.
16 Note that a named block B retains its name after its data block is
17 freed by rmblk(B). That a named block B has null data block may be
18 tested using sizeof(B); this returns 0 if and only if the memory
