Defined in header
<cfenv>
int feupdateenv( const std::fenv_t * envp )
(since C++11)
First, remembers the currently raised floating-point exceptions, then restores the floating-point environment from the object pointed to by envp (similar to std::fesetenv ), then raises the floating-point exceptions that were saved.
This function may be used to end the non-stop mode established by an earlier call to std::feholdexcept .
[edit] Parameters
envp
-
pointer to the object of type std::fenv_t set by an earlier call to std::feholdexcept or
std::fegetenv or equal to FE_DFL_ENV
[edit] Return value
0 on success, non-zero otherwise.
