NAME

abort − generate IOT fault

SYNTAX

int abort()

DESCRIPTION

The abort subroutine executes the PDP11 IOT instruction.  This causes a signal that normally terminates the process with a core dump, which may be used for debugging. 

It is possible for abort to return control if SIGIOT is caught or ignored.  In this case, the value returned is that of the kill(2) system call. 

DIAGNOSTICS

If SIGIOT is neither caught nor ignored, and the current directory is writable, a core dump is produced and the message "IOT trap -- core dumped" is written by the shell.
