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.
