fp_flush_imprecise Subroutine

Purpose

Forces imprecise signal delivery.

Library

Standard C Library (libc.a)

Syntax

#include <fptrap.h>

void fp_flush_imprecise ()

Description

The fp_flush_imprecise subroutine forces any imprecise interrupts to be reported. To ensure that no signals are lost when a program voluntarily exits, use this subroutine in combination with the atexit (exit, atexit, unatexit, _exit, or _Exit Subroutine) subroutine.

Example

The following example illustrates using the atexit subroutine to run the fp_flush_imprecise subroutine before a program exits:

#include <fptrap.h>
#include <stdlib.h>
#include <stdio.h>
  if (0!=atexit(fp_flush_imprecise))
           puts ("Failure in atexit(fp_flush_imprecise) ");
