Defined in float.h, this function is
provided for compatibility with Microsoft products. It returns the
current value of the exception sticky flags. The _controlfp() argument
macros, for example _EM_INVALID and _EM_ZERODIVIDE,
can be used to test bits of the returned result.
The function prototype for _statusfp() is:
unsigned _statusfp(void);
Note
This function requires you to select a floating-point model
that supports exceptions. For example, --fpmode=ieee_full or --fpmode=ieee_fixed.
