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

SYNOPSIS
     cc [ flag... ] file... -lm [ library... ]
     #include 

     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  argu-
     ment in the object pointed to by the flagp argument.


     The  fesetexceptflag()  function   attempts   to   set   the
     floating-point  status  flags indicated by the excepts argu-
     ment to the states stored in the object pointed to by flagp.
     The value pointed to by flagp will have been set by a previ-
     ous  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,  fegetex-
     ceptflag()  returns  0.  Otherwise,  it  returns  a non-zero
     value.


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

ERRORS
     No errors are defined.
