I have written a TSR in DJGPP C++ which functions as network interface. The
TSR itself answers an IPX callback routine and has an API interrupt. One of
purposes of this program is to interpret the terrible IPX packets - Yup I
did it - and stuff them into an receive queue waiting for a client program
to request it over the API.

The storage queue is the main problem. Since I am writing the TSR in C++ I
would like to let a class dynamically take care of the memory needed for the
saved packets. This means to create a -new- packet in memory in the IPX
callback routine and to -delete- the packet in the API interrupt again.

Is it possible to malloc and free or new and delete memory in interrupts and
callbacks in a TSR???
