Linux 2.6 - man page for fegetexceptflag (linux section 3posix)

FEGETEXCEPTFLAG(P)		    POSIX Programmer's Manual		       FEGETEXCEPTFLAG(P)

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 represen-
       tation 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 indi-
       cated 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. Other-
       wise,  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.  Other-
       wise, it shall return a non-zero value.

ERRORS
       No errors are defined.
