42 system call causes the process to be killed and the specified diagnostic
43 message (with arguments) to be delivered by the kernel to the
51 terminated string specifying a reason of the program's termination

55 array contains pointers which will be logged numerically
62 argument specifies the number of pointers in
69 is intended for use in situations where continuation of a process
70 is impossible or for other definitive reasons is unwanted, and normal
71 diagnostic channels cannot be trusted to deliver the message.
