The function tracing-state returns a listing describing the current state of the tracing system. It shows the current tracing state for the dspec dspec , or for all traced definitions if dspec is not supplied.
The result
state
is a list each element of which is a list whose car is a dspec naming the traced definition and whose cdr is the additional trace options. Note that
tracing-state
returns more information than is returned by trace. It is useful for preserving a complex set of traces.
The function
(setf tracing-state)
sets the state of the tracing system. It changes the current tracing state for the dspec
dspec
, or for all traced definitions if
dspec
is not supplied.
(setf tracing-state)
can be used to switch between different sets of traces. Note however that turning tracing omn or off is better done using tracing-enabled-p.
