The T-Kernel defines task exception handling functions for dealing with exceptions. Note that CPU exceptions are treated as interrupts.
A task exception handling function invokes a system call requesting task exception handling by a designated task, interrupts execution by the specified task, and runs a task exception handler. Execution of the task exception handler takes place in the same context as the interrupted task. Upon return from the task exception handler, the interrupted processing continues.
One task exception handler per task can be registered from an application.
