| SYNOPSIS |
#include <fenvtrap.h> int fesettrapenable(int traps);
| DESCRIPTION |
fesettrapenable is used
to define which floating-point exceptions will cause trapping. The traps argument should be zero for no trapping or the sum
of one or more of the exception names defined in fenv.h.
| RETURN VALUE |
fesettrapenable has no
return value.
| CAUTIONS |
fesettrapenable returns
-1 when called from a function whose default floating-point format is hexadecimal,
that is, one compiled without the bfp option.
A program which calls fesettrapenable
must use the standard FENV_ACCESS pragma in an enclosing scope, or the effects
are unpredictable.
