There is a global 32-bit trace mask: the low 16 bits are the global
trace output types, while the upper 16 bits are the per-object trace
output types. Each object has a similar trace mask. The upper 16
bits of the global trace mask are not defined, but can be used to
set the per-object output types for all objects. To enable all trace
output types for all objects, set the global trace mask to all 1s
(i.e., -1).
The MEITrace{...} enum (declared in trace.h) specifies the
global types of trace output, i.e., the types of trace output that
can be produced by any object or module. The MEITrace{...}
enum defines constants that you use together as a bit mask. You
specify the desired trace output as a combination (logical OR) of
MEITrace{...} constants.
There are 16 possible types of global trace output, with 12 global
trace outputs defined.
