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 sta‐
       tus 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  excep‐
       tions 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.
