NAME
fesettrapenable() — set exception trap enable bits
SYNOPSIS
#include <fenv.h>
void fesettrapenable(int excepts);
DESCRIPTION
The
fesettrapenable()
function sets the exception trap enable bits indicated by
the argument

The argument can be constructed as a bitwise OR of the
exception macros:
FE_INEXACT,
FE_DIVBYZERO,
FE_UNDERFLOW,
FE_OVERFLOW,
and
FE_INVALID.
FE_ALL_EXCEPT
represents all the exceptions.
The function also clears the trap enable bits for any exceptions not
indicated by the argument
excepts.
To use this function, compile either with the default
-Ae
option or with the
-Aa
and
-D_HPUX_SOURCE
options. Make sure your program includes
