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.
