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  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.
