Description

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 on or off is better done using tracing-enabled-p.
