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 dif-
       fer (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 implementation-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 represented 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  successfully  set,
       fesetexceptflag() shall return zero. Otherwise, it shall return a non-zero value.

ERRORS
       No errors are defined.
