NAME
|
|
isblk - whether or not a value is a block
|
|
|
|
SYNOPSIS
|
|
isblk(val)
|
|
|
|
TYPES
|
|
val any
|
|
|
|
return 0, 1, or 2
|
|
|
|
DESCRIPTION
|
|
isblk(val) returns 1 if val is an unnamed block, 2 if val is a
|
|
named block, 0 otherwise.
|
|
|
|
Note that a named block B retains its name after its data block is
|
|
freed by rmblk(B). That a named block B has null data block may be
|
|
tested using sizeof(B); this returns 0 if and only if the memory
|
|
has been freed.
