+@deftypefun int feraiseexcept (int @var{excepts})
+This function raises the supported exceptions indicated by

+the order in which the exceptions are raised is undefined except that
+overflow (@code{FE_OVERFLOW}) or underflow (@code{FE_UNDERFLOW}) are
+raised before inexact (@code{FE_INEXACT}). Whether for overflow or
+underflow the inexact exception is also raised is also implementation
+dependent.
+
+The function returns zero in case the operation was successful, a
+non-zero value otherwise.

This function stores in the variable pointed to by @var{flagp} an

This function restores the flags for the exceptions indicated by
@var{excepts} to the values stored in the variable pointed to by
@var{flagp}.
+
+The function returns zero in case the operation was successful, a

@comment ISO
-@deftypefun void feupdateenv (const fenv_t *@var{envp})
+@deftypefun int feupdateenv (const fenv_t *@var{envp})
Like @code{fesetenv}, this function sets the floating-point environment
to that described by @var{envp}. However, if any exceptions were
flagged in the status word before @code{feupdateenv} was called, they
remain flagged after the call. In other words, after @code{feupdateenv}
is called, the status word is the bitwise OR of the previous status word
and the one saved in @var{envp}.
+
+The function returns zero in case the operation was successful, a
+non-zero value otherwise.
