The feholdexcept() function shall save the current floating-point
environment in the object pointed to by envp,
clear the floating-point status flags, and then install a non-stop
(continue on floating-point exceptions) mode, if available, for
all floating-point exceptions.
The feholdexcept() function shall return zero if and only if
non-stop floating-point exception handling was successfully
No errors are defined.
The following sections are informative.
The feholdexcept() function should be effective on typical IEC 60559:1989
standard implementations which have the
default non-stop mode and at least one other mode for trap handling
or aborting. If the implementation provides only the non-stop
mode, then installing the non-stop mode is trivial.
