NAME

abort − generate an illegal instruction fault

DESCRIPTION

The abort subroutine executes an instruction which is illegal in user mode. This causes a signal that normally terminates the process with a core dump, which may be used for debugging.

ENVIRONMENT

When your program is compiled using the System V environment, abort closes open files before aborting the process with an IOT fault.

RESTRICTIONS

The abort function does not flush standard I/O buffers.  Use fflush(.). For further information, see fclose(.).

DIAGNOSTICS
