after cancel id
Cancels the execution of a delayed command that was previously scheduled. Id indicates which command should be canceled; it must have been the return value from a previous after command. If the command given by id has already been executed then the after cancel command has no effect.
- after cancel script script script ...
- This command also cancels the execution of a delayed command. The script arguments are concatenated together with space separators (just as in the concat command). If there is a pending command that matches the string, it is cancelled and will never be executed; if no such command is currently pending then the after cancel command has no effect.
