The feupdateenv function saves the currently raised exceptions in

its automatic storage, installs the floating-point environment
|
|
represented by the object pointed to by envp, and then raises the
|
|
saved exceptions. The argument envp shall point to an object
|
|
set by a call to feholdexcept or fegetenv, or equal the macro
|
|
FE_DFL_ENV or an implementation-defined environment macro. */
