First, remembers the currently raised floating-point exceptions, then restores the floating-point environment from the object pointed to by envp (similar to Template:cpp), 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 Template:cpp.
Parameters
| envp | - | pointer to the object of type Template:cpp set by an earlier call to Template:cpp or std::fegetenv or equal to Template:cpp
|
Return value
Template:cpp on success, non-zero otherwise.
