DESCRIPTION¶
API¶
- debug heartbeat ?delta?
- This method activates or disables a heartbeat with which to monitor the
event loop of an event-based Tcl application.
It reserves the debug tag heartbeat for its operation and writes a
message every delta milliseconds.
A delta-value <= 0 disables the heartbeat.
The message produced by the heartbeat contains a sequence counter and the
time in milliseconds since the last beat, thus providing insight into
timing variationsn and deviations from the nominal delta.
