FEGETEXCEPTFLAG(3P)        POSIX Programmer's Manual       FEGETEXCEPTFLAG(3P)
PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       fegetexceptflag, fesetexceptflag -- get and set  floating-point  status
       flags
SYNOPSIS
       #include <fenv.h>
       int fegetexceptflag(fexcept_t *flagp, int excepts);
       int fesetexceptflag(const fexcept_t *flagp, int excepts);
DESCRIPTION
       The  functionality described on this reference page is aligned with the
       ISO C standard. Any conflict between the  requirements  described  here
       and  the  ISO C  standard is unintentional. This volume of POSIX.1-2008
       defers to the ISO C standard.
       The fegetexceptflag() function shall attempt to  store  an  implementa-
       tion-defined  representation of the states of the floating-point status
       flags indicated by the argument excepts in the object pointed to by the
       argument flagp.
       The  fesetexceptflag() function shall attempt to set the floating-point
       status flags indicated by the argument excepts to the states stored  in
       the  object  pointed  to by flagp.  The value pointed to by flagp shall
       have been set by a previous  call  to  fegetexceptflag()  whose  second
       argument  represented  at  least those floating-point exceptions repre-
       sented by the argument excepts.  This function does not raise floating-
       point exceptions, but only sets the state of the flags.
RETURN VALUE
       If  the representation was successfully stored, fegetexceptflag() shall
       return zero. Otherwise, it  shall  return  a  non-zero  value.  If  the
       excepts  argument  is zero or if all the specified exceptions were suc-
       cessfully set, fesetexceptflag() shall return zero. Otherwise, it shall
       return a non-zero value.
