Notes & Comments
- unless the process is its own parent (see AH=26h, offset 16h in PSP), all open files are closed and all memory belonging to the process is freed
- all network file locks should be removed before calling this function
- restores the terminate, Ctrl-Break, and critical error exit addresses, flushes all buffers, frees memory and returns to DOS via the termination handler address
- does not close FCBs
this function is not supported in versions of DOS before 2.x, so use Int 0x21,0x00 or Int 0x20 to exit.
