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.
