Defined in header <<fenv.h>>
int feupdateenv( const fenv_t* envp );
(since C99)

First, remembers the currently raised floating-point exceptions, then restores the floating-point environment from the object pointed to by envp (similar to 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 feholdexcept.

Contents

Parameters
