threads (tasks, software interrupts, and hardware interrupts). For example, memory allocation APIs such as Memory_alloc() and Memory_calloc() cannot be called from within the context of a software interrupt. Thus, if a particular class is instantiated by a software interrupt, its constructor must avoid performing memory allocation.

Similarly, it is important to keep in mind the time at which a class destructor is expected to run. Not only does a class destructor execute when an object is explicitly deleted, but also when a local object goes out of scope. You need to be aware of what type of thread is executing when the class destructor is called and make only those SYS/BIOS API calls that are appropriate for that thread. For further information on function callability, see the CDOC online documentation./*
