FEGETEXCEPTFLAG(3M) Mathematical Library Functions FEGETEXCEPTFLAG(3M)

NAME

fegetexceptflag, fesetexceptflag - get and set floating-point status
flags

SYNOPSIS

cc [ flag... ] file... -lm [ library... ]
#include <fenv.h>

int fegetexceptflag(fexcept_t *flagp, int excepts);


int fesetexceptflag(const fexcept_t *flagp, int excepts);

DESCRIPTION

The fegetexceptflag() function attempts to store an implementation-
defined representation of the states of the floating-point status
flags indicated by the excepts argument in the object pointed to by
the flagp argument.


The fesetexceptflag() function attempts to set the floating-point
status flags indicated by the excepts argument to the states stored
in the object pointed to by flagp. The value pointed to by flagp will
have been set by a previous call to fegetexceptflag() whose second
argument represented at least those floating-point exceptions
represented by the excepts argument. This function does not raise
floating-point exceptions but only sets the state of the flags.

RETURN VALUES

If the representation was successfully stored, fegetexceptflag()
returns 0. Otherwise, it returns a non-zero value.


If the excepts argument is 0 or if all the specified exceptions were
successfully set, fesetexceptflag() returns 0. Otherwise, it returns
a non-zero value.

ERRORS

No errors are defined.
